I built a arduino based car. At first i wanted it to be rc but i accedantally broke the ir reccevier and i switched to a ultra sonic sensor so if it detects a object in front of it, it will try to avoid it.I used for this project things you can find in your home(instead of the arduino,ULN2003 and HC-SR04) beacus i wanted to show that you can do hardware projects without spending a lot of money and that you just need to look around you.
