Can I connect 4, 12v DC motors to arduino Uno?
What is motor driver ?
I read that the UNO board have 6 pwm, that mean that I can connect 6 motors, or two?
If I understand the pwm connect to motor driver and than the motor driver control the motor by extranl power source?
And I saw that most of the motor drivers can handle up to 2A, what I can do if the motor needs more than 2A ?
