Story

This is a game that has a light bouncing back and forth along a row of LEDs. Push the button when it is in the middle to level up. Work your way through twenty levels to win!
This project uses an Arduino Mega 2560 with a lego casing and plexiglass cover. The sounds are run by a piezo speaker, and there are seventeen LEDs along a breadboard with 300 ohm resistors.
1 / 3
Because I needed a long button to reach through the lego wall and out to where the user could push it, I utilized a rotary encoder's sw pin and push-button.
Most of the sounds run are not musical, but sirens, buzzers, etc. I did not spend much time creating the sound program parts, the speaker was an addition to the original project.
This is a short write-up, and as in my previous projects there is a longer one at my site here.
