Hi, I'm a total noob and have an Owi (edge) robot arm which uses 5 x 3V motors. The circuit board is damaged (my fault) so I want to use an Arduino Uno to control it.
I have 2 options, one is to control the existing motors but I'm confused how to do this as. I've seen that there are motor shields but they only seem to control up to 4 motors (in both directions) and I need to control 5, is it possible to plug 2 motor shields into each other or would I need to my own circuit using a breadboard?
The other option and the one I would prefer is to replace the existing motors with servos so I can create a feedback loop. Can these be plugged directly into the Arduino or do I need a shield and again would this be limited to 4 servos as it is with the motor.
I guess what I want to know is what parts I need to get started. I'm not stupid and once I have a starting point I should be able to sort it out myself (I hope).
Thanks in advance for any help you can give.
