I originally used a 555 timer to advance the count but the circuit got disconnected. It is controlled using two buttons to advance the counter and reset. The circuit has currently changed to use an Arduino micro and is running a "birthday cake" demo program that draws a cylinder and places candles randomly around the top.Īnother of my circuits involves two "seven segment" LED displays (the ones usually found in digital clocks) and two driver chips to count up to 99. It is played using 3 buttons to move left, right and shoot. The one shown to the left is a "space invaders" game I programmed to run on a small 2" TFT screen and Arduino. These are some of the projects/experiments I did in elementary school involving solderless breadboards, Arduinos, integrated circuits, etc.
