It's good to become familiar with the motion sensor, so first set up a breadboard according to the instructions here. You can use either a 3 or 4 battery set-up, so don't panic when you see two battery cases. Have fun waving your hand around. Make sure you try moving the bracket as suggested in the "Triggering" section, so you understand how the sensor works.
