After being able to light up a push button LED, we were asked to make a creative switch. I decided to try toggle switch, when switch to one side, one of the LED lights up, when switch to another, another LED lights up. But then I failed. Both LED lights up when switch is on one side. Which is not what I want. My good classmate Tushar came over and helped me with the sketch and board.
This second one was a flat iron switch! When the two ends touch together, LED lights up. I grab some aluminum foil from the shop and wrap them around the iron. Then place two wires to each side respectively.
The third one was a swiper switch, that when card is swiped across swiper, LED lights up. The shapes were created using laser cutter. I assembled them and included coil tapes and jumper wires.
