Thanks. zapgrap. On the other end of the Bluetooth Communication, I will be using a Smart Phone and a simple Android App to control the Robotic Car. If you are beginner, then building a robot (like a car or an arm) is probably one of the important projects to do after learning about the basics. Also, I have provided a simple Bluetooth Controller App, which can be installed on your Android Phone and start transmitting the data. I have provided information about L298N Module in an earlier project called Arduino DC Motor Control using L298N. You can use either this one or L293D Motor Driver Module. If you are using L293D, then check out for the connections.http://www.easydaytours.com/upload/black-and-decker-bread-machine-manuals.xml

The RX pin of the Bluetooth is left open. Both the Enable Pins are connected to 5V through provided jumper. Since L298N has slots for only two motors, I have joined the left side motors as one set and the right side motors as other set and connected both these sets to the output of L298N Module. To download the app, please refer to that tutorial. If you understood the HC-05 Bluetooth Module tutorial, then understanding the Bluetooth Controlled Robot project is very easy. The corresponding data associated with each key is as follows: Arduino will then make IN1 and IN3 as HIGH and IN2 and IN4 as LOW to achieve a forward motion. If the power is not sufficient, even though the Bluetooth Module powers on, it cannot transmit data or cannot be paired with other Bluetooth devices. You now have items in your Shopping Cart.

The 4WD multifunctional smart car newly upgraded by the Keyestudio Group is one of the most popular categories: programming robots. It is not only beautiful in appearance, but also powerful in function.Except for the commonly used functions of tracking, obstacle avoidance, remote control, etc.,a facial expression is added too, you can DIY your own cute expression, amazing. If you think it’s not enough, you can add other sensors to complete your exploration journey. The 4WD BT Robot Car obstacle avoidance system is formed. The Windows version also has two options,for one option that we could directly click on “install” to download the file. Another choice is to download the file to the computer firstly, then extract the file, and open the program file of the ARDUINO icon to start. Before using it, we need to install the driver of the REV3 development board, otherwise it will not be used. The driver file can be used of the drivers file in the link, or the built-in drivers file can be used too after installing.

There are some small differences for installing driver on different computer systems. Next, we introduce the method of installing the driver in the WIN 7 system. Firstly connect the development board to the computer, click on Computer--Properties--Device Manager to display the following figure. Click “Unknown device” to install the driver, as shown below. Enter this following page and choose: Find the drivers folder for the installation of Arduino. Complete driver installation, click “Close” as shown below This drive is installed. Click on Computer--Properties--Device Manager, we can see the following figure. In the previous lesson, we successfully installed the driver for the REV3 development board. In this lesson, let's learn how to use the Arduino IDE software. We open the folder with decompressed ARDUINO development software and click the ARDUINO icon to open the software.Once the software starts, you have two options. Create a new project. Open an existing project example.To avoid any errors when uploading the program to the board, you need to select the correct Arduino board.Step 4: Select the serial port. Select the serial device of the Arduino board. We can find the corresponding COM port by clicking Computer--Property-Device Manager.Firstly we open the folder with decompressed ARDUINO development software and find the libraries folder. Then place the corresponding folder with the library file in the libraries folder. This library file is installed. Note: If the Arduino IDE software is already open when the library file is placed, need to close the Arduino IDE and re-open the Arduino IDE. The library file will take effect, otherwise the library file will be invalid. Specific methods you can refer to: Firstly we need to download a Mixly software. More info please check the link to download the Mixly blocks software.

It is a free open-source graphical programming tool for creative electronic development; a complete support ecosystem for creative e-education; a stage for maker educators to realize their dreams.The import, export, and editing of library files are shown below:If this is your first experience tinkering with the platform, the REV4 is the most robust board you can start playing with. Well, let's at first have a look at this REV4 board. In fact, slave the output devices under the SPI bus host. When connecting to PC, program the firmware to ATMEGA328P-PU.If LED is off, connection is wrong. Or used as digital output pin to drive different modules like LED, relay, etc. The pin labeled “?” can be used to generate PWM. Used with analogReference().Connected to ATMEGA 16U2-MU. When connecting to PC, program the firmware to ATMEGA 16U2-MU. You can use the RESET button. When the pin is HIGH value, the LED is on, when the pin is LOW, it's off. All you needed to do is connecting the USB port to PC using a USB cable.When Arduino board communicates via serial port, send the message, TX led flashes.When Arduino board communicates via serial port, receive the message, RX led flashes.The number printed on the top of the Arduino crystal is 16.000H9H. It tells us that the frequency is 16,000,000 Hertz or 16MHz.Convert an external input DC7-12V voltage into DC 5V, then switch DC 5V to the processor and other components.Use it less.The function is the same as reset button (labeled 9)Maximum current draw is 50 mA.These pins can read the signal from analog sensors (such as humidity sensor or temperature sensor), and convert it into the digital value that can read by microcontrollers)You can regard it as the brain of your board. The main IC (integrated circuit) on the Arduino is slightly different from the panel pair. Microcontrollers are usually from ATMEL. Before you load a new program on the Arduino IDE, you must know what IC is on your board.

This information can be checked at the top of IC.Servo motor is a position control rotary actuator. It mainly consists of housing, circuit board, core-less motor, gear and position sensor. Included with your servo motor you will find a variety of white motor mounts that connect to the shaft of your servo. You may choose to attach any mount you wish for the circuit. It will serve as a visual aid, making it easier to see the servo spin.The receiver or MCU outputs a signal to the servomotor. The motor has a built-in reference circuit that gives out reference signal, cycle of 20ms and width of 1.5ms. The motor compares the acquired DC bias voltage to the voltage of the potentiometer and outputs a voltage difference. Servo motor comes with many specifications. But all of them have three connection wires, distinguished by brown, red, orange colors (different brand may have different color). Brown one is for GND, red one for power positive, orange one for signal line.The standard cycle of PWM signal is 20ms (50Hz). But note that for different brand motor, the same signal may have different rotation angle. Extension Practice: In the process of smart car DIY, the ultrasonic module is a very commonly used sensor module. The module can detect whether there is obstacle ahead. We can also know about the distance between the smart car and the obstacle through calculation. The smart car is controlled by the the distance that the ultrasonic detects, so as to realize various functions, such as automatic avoiding, following, etc. In the experiment, we test the corresponded distance by detecting the ultrasonic module and the obstacle ahead, and display on the serial monitor.

In the experiment, we use the USB cable to supply power, upload the test code, open the serial monitor and set the baud rate to 9600, we can see the distance between the ultrasonic module and the obstacle ahead ( cm), as shown below: Knowledge The library file has been fixed to the wiring port, and the interface cannot be changed.Extension Practice. We can test the data measured by the ultrasonic to control the angle of rotation of servo. For example, when the distance is less than 15cm, set servo to 60?; when the distance is greater than or equal to 15cm, set servo to 120?. This is a smart car kit with built-in an 8x16 LED light board that can be used to display various states of the smart car. Firstly let's learn the next 8x16 LED board. The 8x16 LED board comes with 128 LEDs and an AIP1640 chip. We can use the MCU and this module for I2C communication. To facilitate wiring, we also provide a HX-2.54 4Pin wiring.In the code, we have set the display state of the LED matrix in the library. Set the delay time to control the display frequency of LED matrixThe component used here is the TCRT5000 infrared tube. Its working principle is to use the different reflectivity of infrared light to the color, then convert the strength of the reflected signal into a current signal. During the process of detection, black is active at HIGH level, but white is active at LOW level. The detection height is 0-3 cm. The keyestudio 3-channel line tracking module has integrated 3 sets of TCRT5000 infrared tube on a single board, which is more convenient for wiring and control. By rotating the adjustable potentiometer on the sensor, it can adjust the detection sensitivity of the sensor. When adjust the LED at the threshold between ON and OFF, the sensitivity is the best. In the code, it means that if condition 1 is met, the result is A, otherwise the result is B. When using it, you only find it on Mixly sentences,click blue gear icon, then drag to block. Set successfully.

In the experimentis logic sentence, it is required to meet one of three requirements. Extension Practice Control the servo to rotate at different angles. It's hard to imagine our world without it. In reality, an infrared remote control can be used to control a wide range of home appliances such as television, audio, video recorders and satellite signal receivers. Well, in the following let’s get a better understanding of the infrared remote control. Infrared remote control is composed of infrared transmitting and infrared receiving systems. That is, consist of an infrared remote control, an infrared receiver module and a microcontroller that can decode. It is composed of a pilot code, user code, data code, and data inversion code. The time interval between pulses is used to distinguish whether it is a signal 0 or 1. (when the ratio of high level to low level is about 1:1, considered as signal 0.) And the encoding is just well composed of signal 0 and 1. The user code of the same button on remote controller is unchanged. Using difference data distinguish the key pressed on the remote control. When press down a button on the remote control, it will send out an infrared carrier signal. And when infrared receiver receives that signal, its program will decode the carrier signal, and through different data codes, thus can judge which key is pressed. The microcontroller is decoded by an received signal 0 or 1 to determine which key is pressed by the remote control. As for an infrared receiver module, it is mainly composed of an infrared receiving head. This device integrates with reception, amplification and demodulation. Its internal IC has been demodulated, able to complete all the work from infrared reception to output TTL level signal compatible. It outputs Digital signal. Suitable for IR remote control and infrared data transmission.

The infrared receiver module has only three pins (Signal line, VCC, GND), very convenient to communicate with Arduino and other microcontrollers.In the experiment, we use the USB cable to supply power, upload the test code, open the serial monitor, set the baud rate to 9600, take out the remote control which points to infrared receiving sensor to send the signal. The key value of the corresponding button is shown. If pressed for long time, error codes will appear, as shown below. If the forward value of the infrared remote control is received, the dot matrix displays the forward pattern. If the key value of infrared remote control is “OK”, pattern “STOP”appear. We made a remote control button value table through the obtained values, which is convenient for future use. Knowledge There are many ways to drive the motor. Our robot uses the most commonly used L298P solution. L298P is an excellent high-power motor driver IC produced by STMicroelectronics. It can directly drive DC motors, two-phase and four-phase stepping motors. The driving current up to 2A, and output terminal of motor adopts eight high-speed Schottky diodes as protection.The stackable design can make it be plugged directly into the Arduino, reducing the technical difficulty of using and driving the motor. Direct stack the motor driver shield onto REV4 board, after the BAT is powered on, turn the Slide switch ON, to supply the power for both keyestudio motor driver shield V2 and REV4 board. For simple wiring, the motor driver shield comes with anti-reverse interfaces. When connecting the motor, power supply and sensor modules, you just need to plug in directly. When connecting, just plug HM-10 Bluetooth module into the corresponding interface. The motor drive shield can access to 4 DC motors, defaulted by jumper connection. The motor connector A and A1, connector B and B1 are separately in parallel.

For instance, if change the 2 jumpers near the motor A connector from horizontal connection to vertical connection, the turning direction of motor A is opposite to the original rotation direction.Logic part input voltage: DC5V. Driving part input voltage (limit): DC 6-18V. Driving part input voltage (recommended): DC 7-12V. Driving part input voltage: DC 7-12V. Logic part working current: PIN Instructions: According to the wiring diagram, default the jumper connection method. Follow the table below to drive the 2 motors rotate by Digital, PWM pins, so as to control the robot car run. The PWM value is in the range of 0-255. The greater the value set, the faster the motors rotate. The length of code is saved.Extension Practice. Reset the movement track of robot car through the library,so as to drive running according to your requirements. There are M1 M2 M3 M4 interfaces on acrylic board correspond to 4 ports of motor on the drive board. As shown below. 12.The 8 jumper caps and the Keyestudio HM-10 Bluetooth-4.0 are plugged into the motor driving board and the installation is complete. Note: when uploading the test code, you need to remove the Keyestudio HM-10 Bluetooth-4.0, and then reconnect the code after successfully uploading, otherwise the upload code fails.In the above sections we already introduced the various sensors, modules, and expansion board and other hardware. In the project, we make the robot detect black line at the car bottom with line tracking sensor. Then control the 2 motors rotation by measured result, so as to drive the robot track black line.We start making smart cars according to the design ideas. We need to design the corresponding wiring, test code, then upload code and run to ensure that the smart car can achieve the ideal function.Stack the expansion board on the REV4 board and wire it according to connection diagram. After power-on, the DIP switch will be dialed to the “ON” end, and the smart car can walk along the black line.

In the circuit process, we can make use of ultrasonic sensor to detect the distance between robot car and front obstacles. Control the motor rotating by measured data, thus control the motion of robot car. The specific logic of ultrasonic follow robot car is as shown below:We need to design the corresponding wiring, test the code, and then wire and upload code to drive, ensuring that the smart car can achieve the ideal function.In the circuit process, we can make use of ultrasonic sensor to detect the distance between robot and front obstacles. Control the motor rotating by measured data, thus control the robot motion and show the running state by dot matrix. The ultrasonic avoiding capability is almost the same as the ultrasonic following function. We only need to change the source code.We need to design the corresponding wiring, test the code, then wire and the upload code to drive, ensuring that the smart car can achieve the ideal function.After uploading the code on the REV4 board, wire according to connection diagram. After the DIP switch is dialed to the right end, the smart car can automatically avoid obstacles.In the IR receiver section, we’ve listed out each key value of remote control. In this circuit design, we can set the key value in the code to navigate the robot car movement. The corresponding state pattern is displayed on the 8X16 LED matrix.At the same time, the 8X16 LED light board displays the corresponding state pattern.For a control smart robot, there should be a control terminal and a controlled terminal. In the course, we use the mobile phone as the console (host), and the HM-10 Bluetooth module (slave) connected to the robot as the controlled terminal. When using it, we need to install an APP on the phone, and connect the HM-10 Bluetooth module, then we tap the buttons on the Bluetooth APP to navigate the various motion states of robot car.

When use as the Host, it can send commands to the slave actively; when use as the Slave, it can only receive commands from the host. In the experiment, we default use the HM-10 Bluetooth module as a Slave and the cellphone as a Host. We install the Bluetooth APP on the mobile phone, connecting the Bluetooth module; finally use the Bluetooth APP to control the robot car move, or to control the working status of other sensor modules on the robot car. We provide you with 2 types of mobile APP, for Android and iOS system. In the experiment, connect the Bluetooth module by mobile Bluetooth APP, tap the front button on the Bluetooth APP to control the LED matrix displaying front image; release the button, display the “STOP”.

This project is a bluetooth controlled robot. This android application could be downloaded in the android market. The wireless communication techniques used to control the robot is bluetooth technology. User can use various commands like move forward, reverse, stop move left, move right. These commands are sent from the Android mobile to the bluetooth receiver which is interfaced with the Arduino robot. The microcontroller then transmits the signal to the motor driver IC’s to operate the motors. This App allows the user to set a UUID of his own bluetooth module in order to connect the android application with his projects.

The default UUID that comes with this application is for the HC-06 Wireless Serial 4 Pin bluetooth RF Transceiver Module RS232. (If you use default UUID in order to pair the BT module with your smartphone for the first time, you will have to give a 4-digit password. This password is '1234'.) There are 8 different gestures available FRONT As the title suggests, this mode is specifically designed to remote control a vehicle which uses a bluetooth module and a microcontroller. The arrow buttons are specifically designed to send commands continuously while pressed, in order to simulate an actual controller. Since Arduino serial port receives one byte at a time, if the user types a string in the input text field, the application divides that string into characters and sends them one by one to Arduino. It should be noted that spaces or empty strings are skipped.
