Yet another illustration, this illustration demonstrates making a remote controlled rover robot base on 433MHz RF Link radio module, Joystick and with L298n and l293d H-Bridge motor controller you can choose which suit to use for the motor controller. As you can see the illustration below their two type of RF configuration one is the receiver and one is the transmitter just follow the illustration below for wiring and connecting the motor controller.


Required Components

  • 2 Arduino UNO/MEGA / NANO
  • RF Link 433MHz  AM (Transmitter & Receiver)
  • Aluminum Box or Cardboard Box / Old Car Toys
  • Joystick Breakout Module
  • Wheels / 4 Wheels to be plug directly to the motors
  • 2 DC Motors or 4 DC Motor ( See the wiring diagram for 4 DC Motors)
    • DC Motor will generate a spike and it disrupt the signal to the communication device, so you need to suppress by using capacitors to all the motors. see the diagram for wiring the motors to the H-Bridge
  • Jumper Wires / 1mm Wires
  • Battery

    There is a small problem idea.
    As the system loses its range it remembers the last command.

    Proszę, aby funkcja …
    jeśli zakres jest poza związanym zerwaniem połączenia i zatrzymaniem silnika.

    Zauważ, że to tylko pseudo kod. :)

    Jeśli (radio == 0) {
    silnik skręt Niski
    silnik b skręcić NISKI
