Step 1: Parts
The parts used for this included the RC car , Arduino micro controller, diodes and a Ping ultrasonic sensor.
Step 2: Wiring in the Arduino
The car I chose was a very simple design. on the radio reciever I used a multimeter to find which lines when high at what times. this allowed me to interface the Arduino with the car with diodes in the path to to protect the Arduino when the car is used with the remote. When the remote is used I have an ON/Off switch mounted on top of the car.
Step 3: Final Testing
After all the componets I tested in both Automatic and manual modes to see the final testing please go to my youtube channel Thejosg77. thanks for checking this out.
