My favorite project I completed in Arduino to IOT was when I made my “Finger Print Scanner”. The prompt was to make my LCD (Liquid Crystal Display)screen say it was scanning your finger print when someone held the FSR(Force Sensitive Resistor). When I first got the LCD screen I had no idea what it was, so I first had to figure out how to use it. Once I learned how to use it I watched multiple videos on how to use a FSR with the LCD. One problem I ran into many times was when my Arduino setup matched the photo I was copying off of and it wasn’t working. It came to the point of me taking all my wires out of my Arduino and restarting. Twice. After the second time of restarting (and Dishon helping) it finally worked. It was a extremely fun but challenging project.
