So the servos came in and due to the holidays I could not get much work done but I managed to hook them up with the magnetic wheels and test them out.
I'm using the Arduino servo library so that I can control the servo in both directions. The servos have been modded for continuous rotation. I'll upload the source code later. I am currently travelling and updating this blog post via the blogger app.
I have lost one set of magnetic wheels during my travels but that's okay. I will work on the rest of the wall crawler while i wait for new ones to arrive.
