With the task of turning on LED lights without physically pushing the switch with my finger, I chose to extend out the two wires that connect the two LED lights. When the two ends of the wires touch, both of the LEDs light up, like seen in the picture above.
I applied this very simple concept to the act of “cheering” of two people bumping their glasses together. I connected the two ends of the wires to conductive tape and covered two plastic cups with it. Thus electricity flows all around the surface of the two cups and when the tow cups are in contact, the two LEDs light up.
One challenge I faced was figuring out how to connect the LEDs in parallel so that they light up brighter than they do when they are connected in serial. I haven’t been able to figure out how to do so, thus the lights are half as bright as it could be when they are connected in parallel.
