hello all, I am new to this forum and im looking for help on my school electronics project. I am making a small car for children to drive along in the road and it should have something interesting and new. So far i have designed a circuit with thyristors so if the child has a freind with one of these cars they can crash into each other and each time a LED will light up. I need 3 new ideas (and circuit ideas if possible) asap Thanks Chris m
