The final for my electronics class, we have to salvage parts and turn them into something that works. We can modify or create something new. I'm taking the truck and adding a motor ripped from one of the old cinema cameras, so it drives forwards when you flick a switch. My other idea was make the motor reverse the truck, and have the backup beeping sound play as it reverses. On top of all that, I want to add a bigger speaker. I hope I can find one that can run off the same power supply that I'm gonna use to run the motor.
