Otto - build you own robot in two hours!
I used a 100 Ohm Resistor to control the Base of the N2222 Transistor. Both a 1000 Ohm and 220 Ohm the motor could not develop enough starting current. The 100 Ohm provided good control and enough starting power. Thank You for the Great Lesson.
Getting Started with Robots
Your Yellow wire coming from Pin9 AnalogOut is not going to your Center Pin of your Transistor, this controls the output of the transistor. Without that connection, your transistor will not allow any voltage to flow to ground from the motor. I would suggest checking your wire connections with the schematic on the Autodesk Circuit Example.
Your First Experiments
Thank You Becky for a Very Nice Introduction to the Arduino and Simple LEDs. I ran through many different code examples and enjoyed the simple ease which you can use to turn teh LEDs on and off, along with the Fade Control.
