![]() ![]() 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. Source Codeįor this example we need to install the RF24 library.Arduino Bluetooth Car offers two kinds of control modes, Compact and Racing. 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 First of all when the app launches, you have to scan and connect to your Bluetooth device/module/receiver (HC-05, HC-06, or any). Code from the Arduino Robot Car // Read the incoming data from the Joystick, or the master Bluetooth device while ( Serial. How to Work Arduino Bluetooth Controller for RC Cars. Materials needed: - RC car - Arduino UNO (or similar) + USB cable for it - BlueSMiRF module - S7V7F5 voltage regulator module - 1500 uF capacitor (or 1000 or 2200) - wires with pins for Arduino - solder. 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. This page explains how to modify an RC car toy so that it can be controlled over Bluetooth and how to configure the RoboRemo app for it. 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.
