ADAFruit Motor Shield

by TomTheTeacher on Sat Dec 01, 2012 1:50 pm

Greetings,

My students and I are building an SROV. We have your 4 Motor Shield using an Arduino UNO. Can I use my Arduino Ethernet Shield stacked between the two? Otherwise, how can I control a motor real-time?

Thanks in advance.

You can use another shield between them if it is built with stacking headers. http://www.adafruit.com/products/85
The Wing Shield comes with stacking headers and is a great way to interface sensors. http://www.adafruit.com/products/196
Whenever you combine shields, you have to be aware of potential pin conflicts. Pin usage on the motor shield is detailed here: http://learn.adafruit.com/adafruit-motor-shield/faq

Hi Tom,
I used a Motorshield to turn a remote control vehicle into a robot. Then I was left with an unused remote control and the vehicle still had a receiver. I wanted to be able to change the robot parameters on the fly so I used the remote control receiver as inputs to the analog pins. I had some trouble with noise, so I used extra stacking headers on everything except the analog pins. This raise dthe motorshield off the arduino a little higher. . This allowed me direct access to the analog pins on the arduino and it solved my noise problem.
Hope this helps.
