Arduino Duemilanove and small DC motor, no controller
September 6, 2010
Hello, I'm new into the world of robotics, I don't have much experience with electronics and I'm waiting for my Arduino Duemilanove to arrive.
Will it be OK if I connect this
To one I/O pin (set on output, HIGH) on Arduino and the GND pin, or will the atmega chip burn?
I searched in Google about controlling DC motors, but I haven't got a clear answer on connecting small ones directly.
I see most of the cases require either a controller (transistor or a relay), or servos are used instead of motors. In my point of view, a controller won't be needed because this motor requires little power.
Since servos have more torque, they are used more frequently, but I will be using 4 (or even more) of those small motors on my robot. So, I'm planning to connect 4 of these on the Arduino directly. Is this OK?
