Firstly, download and install an Android emulator to your PC.So it is advised that you check the minimum and required system requirements of an Android emulator before you download and install it on your PC.īelow you will find how to install and run Arduino Bluetooth RC Car on PC: However, emulators consume many system resources to emulate an OS and run apps on it. There are many free Android emulators available on the internet. Arduino Bluetooth RC Car is an Android app and cannot be installed on Windows PC or MAC directly.Īndroid Emulator is a software application that enables you to run Android apps and games on a PC by emulating Android OS. In addition, the app has a content rating of Everyone, from which you can decide if it is suitable to install for family, kids, or adult users. It has gained around 100000 installs so far, with an average rating of 4.0 out of 5 in the play store.Īrduino Bluetooth RC Car requires Android with an OS version of 2.3.3 and up. Source Codeįor this example we need to install the RF24 library.Arduino Bluetooth RC Car is an Android Education app developed by Andi.Co and published on the Google play store. 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.
