Colorful spaghetti wire hell
Started off with just wiring up the 7 segment digit display to learn the layout of the pins turned into a sound activated 10 second count down then added an indicator LED then said screw it and added a passive buzzer and programmed a little melody to it now it counts down the notes instead of by seconds just need to adjust the sensitivity a little it's a bit to sensitive but whatever it was still a fun project and I learned a lot lol
