Wired Connections

The circuit diagram above shows how the components will be wired together inside the brick. This won't be 100% exact in the actual circuit but it's a very close approximation.

A push button will open and close the connection between the batteries to turn the LED on and off. When the button is held down, the LED stays on, and when it’s released the LED turns off.

Battery Power

The circuit will be powered by two small LR 41 coin cell batteries. The batteries are arranged in series to increase the voltage required to power the LED.
