I made some arduino-powered ghosts to put in my windows

## Parts List

### Essential

- 1x [Adafruit Metro Mini](https://www.adafruit.com/product/2590) -- Compatible with Arduino Uno; any Arduino could be used but might require pin changes.

- 2x [8x8 LED Matrix with I2C Backpack](https://www.adafruit.com/product/1051) -- Comes in multiple colors, but the blue can be hard to resolve from a distance.

  - Requires the **Adafruit LED Backpack** and **Adafruit GFX** libraries from the Arduino library manager

  - See [this tutorial](https://learn.adafruit.com/adafruit-led-backpack/1-2-8x8-matrix-assembly) for assembling the backpack.

- [Common Cathode LEDs](https://www.sparkfun.com/products/9853) -- Could be replaced with single-color LEDs. I use about six per ghost.

### Optional

- [Weatherproof Enclosure](https://www.adafruit.com/product/3931)

- [Push Button](https://www.adafruit.com/product/1505) - Fits in one of the enclosure's openings with a little bit of reaming

- [Jumper cables](https://www.adafruit.com/product/266)

- [Male headers](https://www.adafruit.com/product/2671)

- [Protoboard](https://www.adafruit.com/product/589)

## Construction

> ### Warning About the Shape Files

> The inset shapes are not sized to account for cutting kerf, so you will have to handle that. The service I used for cutting, [Send Cut Send](https://sendcutsend.com/) does it for you, but other services may not.

### Pinouts

Each eye needs four out pins. The eyes are not individually controlled

- I2C pins (A4 and A5 on Uno-compatible boards)

- 5V pin

- Ground pin

The backlight uses four out pins:

- Red on pin 6

- Green on pin 9

- Blue on pin 10

- Ground

The push button to change the backlight color uses pins 7 and 8
