Description
16 LEDs Puzzle
The puzzle consists of 16 LEDs, 16 buttons, and an ATtiny404 (or ATtiny204) processor. Each button toggles the state of the LED above it, but it also has the side effect of toggling other LEDs on the matrix, so getting all the LEDs to turn on takes a bit of logical thinking.
For more information see 16 LEDs Puzzle.
