Day 6: Darlington and driving motors

Today, we learned how to use the 2N3904 transistor and 1N4001 transistor to light a Christmas light, next we made a Darlington circuit to drive the motor of our toys. We learned about the TIP120 transistor and that it has a Darlington circuit built inside of it.
