Snake 3D KiCAD

3-D Snake... but polished

Description and Exigence

The basic framework of this project came from the undercity hackathon, where me and my teammates were able to scrapyard a prototype to work. This project is the same project but refined, adding a PCB to better manage wires and audio to better communicate to the user when the snake dies. Some minor software improvements have also been made (such as re-working the moving mechanism when the snake reaches the top pannel).

Here's a pic of our prototype:

Schematic and PCB

During prototyping, one of the hardest parts of the design was making sure all the gpio pins stayed in place! So, I made a pcb to help with wiring.

Here's the full wirings with the raspberry pi:

Firmware

This project is coded in circuitpython to run on a raspberry pi pico. Most of the firmware was written at the hackathon, including the snake's game engine and wrapping mechanisms. With my improvements, a audio mechanism was added, playing a sound when the game is played and a death "game over" sound. Additionally, the joystick movements was revised, however, its effacaciy will only be able to be tested once I build it and get to callibrate the joystick.

CAD

Here it is! It's pretty bare-bones because I want access to all the gpio and other pins for debugging.

Here's what the game will look like with the prototype cad we made at undercity!
