Sandwich Switch - An Unconventional Switch

 

Here is my unconventional switch that activates an LED when I complete my sandwich. I am utilizing the conductivity of the ham, aided by its liquid preservatives, to complete a circuit. I am using a power supply that outputs ~4.9V, a white LED with a forward voltage of 2.688, and my lunch. I used the ideal LED amperage of 0.02mA to arrive at a desired resistance of 110.6 ohms. I used a 100 ohm and 10 ohm resistor for this circuit. However, it wasn’t until after the fact that I realized that the ham will have an innate resistance, reducing my need for accuracy.
