Step 1: Preparing Components :
2 - Transistors BC337 *4 .
3 - RC remote control car .
4 - Arduino UNO board .
5 - Wires .
Step 2: Working
2 - Replace the terminals by Soldering transistors , collector pin to positive , and emitter pin to negative ,and the resistor to the base.
3 - Connect the resistors to the arduino board pins (2,4,5,7) .
4- Connect positive to (5v) pin and negative to (GND) pin .
Step 3: Finally You Get This Shape …….
Step 4: The Code :
Step 5: Application :
1 - Operate the serial monitor .
2 - write the number (8,2,6,4) from key board + Enter.
3 - press (0 + Enter) to stop the car .
, and enjoy .......
