miscellaneous electronics projects:

These are some of the projects/experiments I did in elementary school involving solderless breadboards, Arduinos, integrated circuits, etc.

The one shown to the left is a "space invaders" game I programmed to run on a small 2" TFT screen and Arduino.  It is played using 3 buttons to move left, right and shoot. 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.

Another 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 controlled using two buttons to advance the counter and reset. I originally used a 555 timer to advance the count but the circuit got disconnected.

I also have some additional circuits which are experiments using 555 timers, LEDs and speakers.

A very helpful book that taught me how to build circuits is Make: Electronics by Charles Platt. It explains everything clearly and starts from very basic circuits. I would recommend it highly.
