Unconventional Switch For this unconventional switch, I hooked up a breadboard to my Circuit Playground Bluefruit with an output of 3.3 Volts. The current would then travel through a 2,000 Ohm resistor before reaching an LED that takes up approximately 1.8 Volts. To close the circuit and create a switch, I ran two wires through a glove and cut out holes at my index finger and thumb and coiled the wire's at those points to create a stable point of contact. By closing those fingers, the circuit is closed and the switch operates as intended
