So I worked on my engineering class project which is to build a line following robot. I built it using an ATtiny and used 2 N Channel Mosfets to control two DC motors. This controller is thus far powered by a single 9 volt battery. The problem is that whenever I turn on one motor, it works fine, but when I used two motors, they won't turn on.
So is the problem that the 9 volt battery does not have enough current to drive both motors at the same time? If so, then what type of battery should I use for this project?
Also, in the future, is it better to have two different power supplies when working with project that involves controlling DC motors (one for the motors and the other for the microcontroller)?
