Will Lego 4.5v motor damage Arduino

Hi,

I am very new to Arduino & electronics. Can I drive a 4.5v lego motor from Pin 11 on my Ardiuno. What happens if you put too much load on a digital pin?

Thanks for your help,

Neal.

It won't work and may well damage your Arduino.
Have a look in the playground for stuff on output, mechanical, motors and H-bridges.

Alternatively look here:-

Thank you soooo much! The info and links are great, I just didn't know what to search for, or where to start. Now I do!

Thanks again,

Neal.

Have a look at THIS shield as a solution.
