====== Breadboard Circuits ======
Each of the following circuits are assembled on their own **mini breadboard**:


===== Training Phase Circuit =====
This circuit provides the operator interface (a single pushbutton) which allows the operator to select which phase of the training protocol is being observed. There are four LEDs on this circuit which illuminate to indicate the current training phase.

==== Required Parts ====
  *[1] Miniature breadboard
  *[1] PCB Mount pushbutton
  *[4] LEDs
  *[1] 10k ohm resistor
  *FIXME - Wiring
  *FIXME - Pins/Connectors

==== Required Tools ====


===== 12 Volt Switching Circuit =====
This circuit employs transistors to allow the Arduino's 5 volt output pins to operate 12 volt components. More specifically, the motors used by the **reward dispenser** and the **training coin dispenser**.

===== Optical Detector Circuit =====
This circuit provides power to, and reads the signals from the CrowBox's two reflective **optical sensors**. One of these optical sensors is used to detect the release of a training coin and the other detects coins that have been deposited by birds.
