i had to scrap the rc car idea beacus i dont know how but the ir receptor dosent work but i switched to the first idea that i had and i used a sensor and now when it sees a object in a range of 20cm it will try to go around( i chose 20cm beacus it turns right or left really hard). I mounted everything on the “case” of the car but i left the arduino out beacus i still dont have a way to power it.
