I got this RC car today. It's the cheapest possible model.
I want to make a raspberry Pi project with it (which has its own 5V supply from a power bank).
Is it safe to directly power the motor with the raspberry Pi ? Should I connect a resistance in series first to the motor? If so how much should be the value of the resistance ?
Kind of how we run LED experiments with raspberry ?
Current setup (it came like this) has 3 X 1.5 V AA batteries as input. And it runs pretty fine.
