Troubleshooting
Here's some things to look for if your project isn't working (and for some great illustrations and further explanations of these, see "Common Mistakes when Using a Breadboard" on the Science Buddies site.)
If your motor doesn’t turn on:
1. Check your connections Be sure to double check the coordinates in the instructions to make sure the pins are completely inserted into the matching holes on the breadboard. Make sure components are fully seated in the breadboard. A component should go into the breadboard at least 4-5 mm (or a little less than the thickness of a pencil) when it's fully inserted. Check for shorts. When components get accidentally connected, it can cause a short circuit.
2. Check your power
Make sure your batteries are fully inserted. Make sure your batteries work.
2. Check the direction(polarity) of your transistor and diode
Make sure the flat side of the transistor (3 pins) is facing toward the jumper wires in C10-12. Make sure the grey strip side of the diode is facing near G21.

Sometimes, things break or get lost—it's part of making and tinkering! If you need to replace a part, here is a list of the individual components that make up the Red Hat Co.Lab Light Sensing kit.
