Key and Lock Soda Can

 

Our Unconventional Switch is rather simple setup. It begins with 5 volts of power being fed from our Circuit Board Playground and attached to our standard key, which acts as our conductor. We then slot the key specifically into the Red Bull cap which is the only part of the can that is conductive. The volts channel from the key to the cap and then into the bread board. The current is then fed through our Resistor which is measured to be about 100 Ohms. This gives our LED light the exact amount of voltage it needs to power on at 3 volts. And finally, the circuit is complete and the remaining power is ground.
