Re: hi everyone

for that u have to use Infrared sensors or ultrasonic sensors + microcontroller,
but if u want to keep it simple just use few couple of switches at the edges of the Toy car

Re: hi everyone

you need a small DC motor, with a driver or not. Sensing may be an infred transmitter and detector.
