Since I wanted to make sure that I really understood what was being taught in class, I first started off by trying to set up basic circuits (with a help from the residents). I followed the schematic in the article and all of them worked without any difficulties.
Since I love dancing, I thought it would be fun to make a switch that I can put into/under my shoes and the LEDs will light up in accordance with my dance steps. The switch I made, though required a lot of time and effort, was really simple. I put a sponge, with a hole in the middle, between two aluminum foil (which are connected to the LEDs) so that the foil will become in contact with each other when you squeeze the sponge. Here’s a photo of my super simple switch.
Both the foil and the sponge were very fragile and they kept tearing apart when I tried to connect them with the wires. It took me almost 2 hours to finally made one that didn’t start breaking apart every time I touch or move it.

And the result!
Though my switch looked kinda sloppy, I had a lot of fun playing with it! Can’t wait to start on another fun project like this! Will try to make something that is more interactive next time.
