As if I were a pianist


Oh yes! It is an Arduino exercises time for week 3. Let’s play around with LEDs and buttons!!

Unfortunately, my LED was not working. Without knowing that from the beginning, I had to spend 3 hours doing CIRC-07 over and over. In my mind, I was constantly asking myself: “what the heck is wrong? what am I doing wrong here?” Once I changed my LED to Lassor’s LED, I finally realized that my stupid LED was broken from the beginning. Oh well, thanks Lassor for letting me use his LED for a couple hour.

Here is a “making better” part. I tried to make a shadow of red color, but you would barely see it.

Lastly, I borrowed another botton from Jiani and tried to make LED piano. Hope you had a fun!
