Unconventional Switch: Team 8

 

Alright, our unconventional switch is an earbuds case. This case only tells us its battery level with the integrated LEDs… But what it fails to show is if the earbuds are actually charging when inside the case. Our assumption is that it only charges when the case is closed.

 The purpose of our project is to add an external signal that lets us know if the case is closed and the buds are charging. That signal will be a single LED that lights up when the case closes and turns off when the case opens

Here we are powering a white LED with a CPB. The LED is on a breadboard that is connected to both the CPB and the switch. The switch is made by wrapping aluminum foil all around the top part of the case. 2 small aluminum “legs” are sticking out the sides of the case and the jumper wires are connected to them. Anytime the top part makes contact with the 2 connected sides, current goes through the circuit and the LED is powered.
