building the robot and setting up a Logic Probe

Today started with the assembly of the square bot, this took a couple of hours and was a lot of fun.  It was setup with two engines, 6 gears and four tires.  I also had to set up the controller and the logic sensors.

Once the car was finished I drove it around a bit and moved on to the next part of class.

The next part of class was to set up a transistor logic probe on a bread board with two LEDs.  The set up used a 2N3904 transistor and 3 resistors.  After that I went to begin to make a permanent Logic probe but ran out of time.
