Notes and tests:

1. Make sure tracks are leveled.
2. Start the Logger Pro file "Lab 4a.xmbl" in the Lab 4 folder of Class Notes. Make sure the switch on the motion detector is on the cart setting. Click "Collect" and move the cart in front of the motion detector to test if the movement of the cart is detected by the motion detector.
3. Put the motion detector on the cart setting. You will need to make sure the motion detector is angled just right to create a smooth graph across the whole length of the track.
