An interesting light display using 64 glue sticks and 128 WS2812B RGB LED strips.
Project tutorial by John Bradnam
Small self contained Arduino Pro Mini Simon game
Play three variants of the game Tacoyaki (also known as Lights Out). Full instructions and code included.
Actually it is 128 : 1 saving since the MEGA version defined step_count as a int where as the UNO version defines it as a uint8_t.
After a lot of tries, I managed to get the code to run on an Ardunio UNO. See https://www.hackster.io/john-bradnam/reducing-your-memory-usage-26ca05
I finally got around to making one :-)
My aim was to reduce the size of the final unit and make it no wider than the LED Matrix itself. The software has been modified to fit in a ATTiny85 and I have 3D printed a case for it. You can find my variant at https://www.thingiverse.com/thing:3877685
