![]() Source Codeįor this example we need to install the RF24 library. We can note that these modules use the SPI communication, so compared to the previous example, I had the move the Enable A and Enable B pins of the L298N driver to the pins number 2 and 3 of the Arduino board.You can get the NRF24L01 module on the following Amazon link. Now we can move on to the next method, wireless control of the Arduino robot car using the NRF24L01 transceiver modules. available() >= 2) Code language: Arduino ( arduino ) Arduino Robot Car Wireless Control Using NRF24L01 Transceiver Module Arduino Bluetooth RC Car apk Apk Size, 4.1M App by, Andi.Co Category, Free Education App Content Rating, Everyone Support Android Version. Code from the Arduino Robot Car // Read the incoming data from the Joystick, or the master Bluetooth device while ( Serial. On an Android phone, navigate to Google Play Store and download the Arduino Bluetooth RC Car app.The app will later pair with the HC-05 Bluetooth module once connected to the Arduino/Motor Shield. So here, if the serial has received the 2 bytes, the X and Y values, using the Serial.read() function we will read both of them. We do this because that range, from 0 to 255, can be sent, over the Bluetooth device, as 1 byte which is easier to be accepted on the other side, or at the Arduino robot car. We can note here that the analog values of joystick from 0 to 1023 are converted into a values from 0 to 255 by diving them by 4. We just need to read the X and Y values of the joystick, which actually regulate the speed of the motors, and send them via the serial port to the slave HC-05 Bluetooth device. The code at the master device, or the joystick is quite simple. write(xAxis/ 4) // Dividing by 4 for converting from 0 - 1023 to 0 - 256, (1 byte) range Serial. ![]() YAxis = analogRead(A1) // Read Joysticks Y-axis // Send the values via the serial port to the slave HC-05 Bluetooth device Serial. XAxis = analogRead(A0) // Read Joysticks X-axis begin( 38400) // Default communication rate of the Bluetooth module We will use the same code from the previous tutorial, where we control the Arduino robot car directly using the joystick, and we will make some modifications to it.Īrduino Robot Car Wireless Control using the HC-05 Bluetoothīy Dejan Nedelkovski, */ int xAxis, yAxis As an Amazon Associate I earn from qualifying purchases.

When I go to operate the care the it doesnt respond. I have everything powered up correctly, and the code seems to be fine. 1 x Bluetooth module (HC05 or HC06) Batteries. I recently followed a youTube video for a basic RC Car using hc-05 bluetooth module, motorshield and uno 3. With compact mode simple handling of the car forward, backward, turn left, turn right and brake functions, and racing mode is also smarter bonus, up to general simulate real car behavior control mode: similar car lock and key switch, left / right turn signals, headlights, horn, fast left / right rotation, acceleration / deceleration, and switching Turbo full acceleration.You can get the components needed for this example from the links below: Here is the list of parts we need: 1 x car chassis with motors. Arduino Bluetooth Car offers two kinds of control modes, Compact and Racing.
