Wireless Joystick controlled Robot Car using Arduino, 433Mhz RF and L298N Motor Driver



Wireless Joystick controlled Robot Car using Arduino– In this tutorial, you will learn how to control a Robot Car wirelessly using Arduino, L298N Motor driver, and  433 Mhz RF transmitter and Receiver. The robot control system can be activated and de-activated using the Built-in Joystick push Button.

Depending on the movement of the joystick and the value of the VRx and VRy, the speed of the dc motors can be controlled in realTime which gives you more control over the Robot Car….

This is the 2nd version of the Robot Car.

While in the first version I used an Android cell phone to control the Robot Car using the HC-05 Bluetooth module.

This Tutorial is based on my previous two tutorials.

in this tutorial I explained, how to assemble the robot parts and how to use the L298N motor driver to control the forward, left , right and reverse movement. In this tutorial, I also explained how to control the speed of a dc motor using the pulse width modulation.

While in this tutorial I explained the joystick pinouts, its basic working principle, its interfacing with Arduino, and basic programming to control some led’s depending on the movement of the joystick… If you are a beginner and you have never used the Joystick module and L298N motor driver then I highly recommend you should first watch these tutorials and then you can resume from here.

You know the Transmitter and receiver modules used for controlling the Robot Car offer short-range wireless communication. If you want to increase the range up to 1Km then watch my tutorial on the NRFL01 Transceiver Modules.

Watch this tutorial for the robot parts assembling and connections.

All the connections are exactly the same as explained in my previous tutorial. The only modification that I did is the addition of the 433 Mhz RF receiver module…the VCC pin of the receiver module is connected with the 5 volts…the ground pin of the receiver is connected with the Arduino’s ground…while the data pin of the receiver is connected with pin number 3 of the Arduino… everything else remains the same as explained in the getting started tutorial…

This is the Joystick Transmitter Side, the 433 Mhz RF transmitter VCC pin is connected with the Arduino’s  5 volts, the ground pin of the transmitter is connected with the Arduino ground while the data pin is connected with the Arduino’s pin number 12…

as you can see I have also solder wire with the transmitter to slightly increase the range…while the joystick connections are exactly the same as explained in the joystick getting started tutorial.

  1. hola muy buenas 1 felicitarte por tu trabajo ojala estuviese en español . xd tengo un problemas con esta parte del código
    vw_set_ptt_inverted(true); // Required for DR3100

  2. Hi, I saw your assembly, I like it a lot so I can give it to my granddaughters, but I have seen the code of the assembly, but if you could send me the circuit or diagram of the assembly, it would be very good.
    Thank you very much in advance, greetings

  3. could you pass me the circuit or diagram crap to assemble for my granddaughters and I have seen the code or drive but I have not seen all the connections greetings and thank you very much in advance

  4. Hello there, I am intrigued by the code. Could you please clear up what “buttonf” is exactly and how it actually changes state. I am assuming its the state the button is in.

    Many Thanks
