Video demo HERE

There are 3 modes in my code, but of course these can be changed to anything you want:

1. Demo/Intro
2. 'Rhythm' game: Click the joystick button when all 10 LEDs are showing
3. 'Memory' game: Copy the sequence shown using the joystick

‘Mouse Ears’ are added to prevent curling, and I printed the diffuser with a filament change so the separators are black - this gives a much nicer result because it stops the light bleeding.

Here are the components I used:

• WS2821B: 24 pixel NeoPixel Ring
• WS2821B: 144 pixel/m strip
• Lithium Battery Indicator
• 602 Serial LCD Module
• Ardunio Nano
• Ardunio Nano Prototype Board
• Toggle Switch
• 3-way side witch (x2)
• Type-C USB 5V 1A 18650 TP4056 Lithium Battery Charger
• Dual-axis Joystick
• 2000mAh Li-Po battery

The Ardunio code can be downloaded from my Git repo: https://github.com/itsmakingthings/braintrain-3000
