Anyone has experience in programming a robot (autocar) in C language??

Question

I never learn this and now have to take part in a robotic competition, which the program includes controlling a sensor and 2 motors. No idea how to start.

Answer 1

Start by buying an Arduino kit with different sensors and using Internet tutorials. You'll find anything you need! On AliExpress a good kit is about 20-30$ so not very expensive. Good luck on your work and remember that in this field mistakes are very expensive, in literal meaning.
