Tacoyaki (Lights Out) Game

thingiverse

This game console is a fun way to play three different versions of Tacoyaki (also known as Lights Out) using an Arduino Pro Mini. It features 16 light up push switches, a 2 digit 7 segment display, and a piezo-electric speaker. The included sketch plays the three variants of the game, which can be played by pressing buttons to change the state of nearby lights. The goal is to turn off all the LEDs in under 25 moves. Level 1: Tacoyaki+ In this version, pressing a button will switch on or off itself and its non-diagonally adjacent buttons. The goal is to turn off all the LEDs in as few moves as possible. Solution: a. Press the button beneath each lit light on row 2 to turn it off. b. Repeat step a for rows 3-4, chasing the lights down. Level 2: Tacoyaki+ with wraparound In this version, the board has no edges and every light has four neighbors. Every move changes exactly five lights. Solution: a. Use the following two facts to determine which buttons to press: 1. Press a button and its four neighbors to change an individual light. 2. Check if an odd number of nearby lights are switched on; if so, press the button. b. For each lit light in rows 2-3, press the button above it in row 1 or below it in row 4. Level 3: Tacoyaki In this version, pressing a button will change the state of all LEDs diagonally from it. Solution: a. Number the rows and columns. b. Press buttons on row 2 to switch off lights on row 1: 1. If A1 is on, press B2. 2. If C1 is on, press D2. c. Switch off lights on row 2: 1. If D1 is on, press C2. 2. If B1 is on, press A2. d. Repeat steps a-c for rows 3-4. Other games to consider adding: * Whack-a-Mole * Super Simple Simon
