The Next Level challenge also has a programming challenge part. I did a practice run on programming in the living room today. I wrote a fairly simple little program for the Flex robot to go pick up a hub, deliver it on a little mat and return to the starting location. For fun I also changed the Touch LED colors every time a job is completed and added a TADAH!! sound at the end. It was all done in Robot-C, I’m still getting used to the syntax being quite different from Arduino.
