Owi Robotic Arm Edge Work With Ez-b?

 
#1

can you control more than 2 motors with the ez-b? and do you need multiple hbridges?

#2

Yes and yes.

Check my cloud files for a multiple h-bridge control project and details on how a h-bridge works have a read of this topic.

@aameralis you can use an bridge but there's no position feedback.
Servo control board hack-
You can buy cheap servos , take them apart. glue the pot to the joint. solder the red wire that went to the motor in the servo to the pos on the motor in that joint and same for your ground too. You can then actuate the joint like you would a servo using the motor and gears already built in the arm.
