I'm working on mounting a nerf gun onto a rc car and controlling everything from a Raspberry Pi. I've got all of the actual circuits sorted, so when I complete them, they go (gun fires, car drives).
I need to be able to use the r pi to simply switch on and off each circuit. I want to have it so when I power a gpio pin, it completes the nerf guns circuit and it fires, and the same for all of the car motors.
I have no idea where to start in actually doing this. The nerf gun and the cars motors all run off of 9v.
Is this possible, and if so how? If not is there another board I could use?
