So 'm planning on making a motor shield for my arduino which basically will be controlling 2 small sized DC motors. I want it to run off of a 9 volt battery AND have that battery also run my arduino through a voltage regulator. So far I was thinking of using the SN754410NE Quad Half Bridge as my H-bridge and incorporating that into EAGLE and making the shield.
Now my question is : what other parts should I consider using or maybe should I use a different H-bridge?
Lastly, would I even NEED an H-bridge to make motors JUST move forward like in a line following robot?
