![]() Choose between a continuous or on change data stream. Updates:*****Please visit the tutorial website for the updated Arduino code A flashing light lets you know when the phone is connected to the car, and arrows light up letting you know the car's driving direction. There are also two buttons for front and back lights. A slider bar allows you to control your car's velocity if the car's control circuit has this feature. The app lets you control the car with either buttons or the phone's accelerometer. Visit this site for the Arduino code and control circuit. This is done using a Bluetooth enabled Android phone. The application allows you to control an Arduino based RC car over Bluetooth. Please visit the website before you download the application. The application will not work with a brand new, out of the box RC car. You have to replace the car's stock control circuit with a micro controller. Modul bluetooth pada RC ini menggunakan HC-05, driver motornyah L298N. Aplikasi yang dipakai adalah Arduino Bluetooth RC Car yang dapat diunduh secara gratis pada playstore. Source Codeįor this example we need to install the RF24 library.Download this app named Arduino Bluetooth RC Car.****This application is designed to be used with a MODIFIED RC car. Arduino Bluetooth RC adalah sebuah robot yang dapat mengikuti perintah layaknya mobil remote control yang biasa itu. 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 Code from the Arduino Robot Car // Read the incoming data from the Joystick, or the master Bluetooth device while ( Serial. 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.
