Question about ground (first robot) and dual H bridge
November 19, 2012
I finally built my first robot, loosely based on the start here tutorial and obviously I have tons of question.
This is the motor driver I am using : http://www.geekonfire.com/wiki/index.php?title=Dual_H-Bridge_Motor_Driver
and in the examples the ground of the motor driver is not connected to the arduino's ground.
Is it correct ? Or should I anywway connect both grounds together ?
Also I have a question about the batteries,
I am sorry about that I read a lot about on the forum and I am just more and more confused.
Currently the arduino is powered with 6x1.5v (9v) and the motors with 4x1.5v, which is a lot of batteries I think.
Can I connect both the arduino and the motor driver on the 6x1.5v pack ? I my dual H bridge good enough to handle that ?
