I’ve posted three videos from the second day of class, click the words to view them. There is one on soldering
another on assembling a circuit to power one motor,
and finally a talk Ted gave in our lab on the circuitry and driver chip needed to power two motors for your robot.
I have also posted a video Ted and I made before the semester started about getting the wheels to turn various directions.
They are raw, but we hope they will help in case you need a refresher or missed something in the first go. The following pictures may help, too.
