This project generates random mazes and their solution using an Adafruit Metro M4 Express and an Adafruit ePaper shield. This is a fun, no-solder project suitable for all ages with three difficulty levels to choose from. You will have some a-maze-ing fun with it!

This project does not use WiFi, so it will work with either the Metro M4 Express or the Metro M4 Express Airlift. This project can be made portable by adding a battery, making it a great activity to take on a long car ride to minimize hearing "Are we there yet?" from the back of the car.

The original maze generator code this project is based on was written over 20 years ago in C for printing random mazes on paper. The use of the ePaper shield in this project brings a modern touch to this classic code.

Parts

Building this project requires no soldering and uses just two parts: the Adafruit Metro M4 Express and the Adafruit 2.7" Tri-Color eInk / ePaper Shield with SRAM.  Either the Metro M4 or Metro M4 Airlift Express can be used. To make this project portable, you could use a 9V battery and adapter (shortest battery life) or add a USB battery pack and adapter cable (longer life and rechargeable).
