Use levers as buttons! This is a dual edge detector, which means it pulses every time the state of the input redstone is changed. This design is only 3x2x1, and it uses some strange redstone behavior to make a 0-tick pulse whenever the input state is changed. To increase the pulse length and/or negate the output, you can hook up the output a dropper pointing into a hopper and take a comparator output from either.

Dr. Alphys colored tile maze, from the game Undertale by Toby Fox, is a simple-looking puzzle with intentionally complicated rules. This map contains 25 custom-made puzzles, including both of the only two playable puzzles from Undertale. It also includes a level editor, so you can even design and share your own puzzles!
This map was made in Minecraft 1.8.9. The pre-made levels in this map can be played by up to 4 players, but custom-made levels from the level editor can include many more.

I dont know whether Im allowed to use it in this video but then again the whole map is based on a minigame in Undertale so I may as well go all-in with the copyright infringement.
