Week 7: More problems

-        Still having trouble hooking up the circuit.

Week 6: Sensor Issues

-        Update: keep having trouble hooking up the sensor so need more time

Week 6: Photodetector as switch?

-        Using it as our switch.

Week 5: Optical sensors

Using an optical sensor, the operation of the motor can be controlled by a "disc" with holes that rotates through the sensor. Blocking the infrared that the sensor produces will signal the motor to stop.

Circuit with working optical sensor:

Written program (multiple combined into one):

Update (29/11/2016): Changed to a touch sensor because the optical sensor was too sensitive.

Week 5: Stopping the motor controlling the poppers

A circuit developed to stop the motor from spinning after the power supply is switched off, due to extra torque generated from the motor itself.
