## Demo
> This project was originally built for outdoor use
[](http://www.youtube.com/watch?v=fl52GQJCFVI "pumpkin-pi demo")
## Photos
> Note: Holes in the acrylic case are needed for the motion sensors to properly work
## Wiring diagram
> Created with [circuit-diagram.org](https://www.circuit-diagram.org/). Source file is in [/diagrams](/diagrams)
## Deploy
> Requires following diagram above to be wired up correctly
### Docker
```bash
# This script will install the dependencies and start the containers
bash -c "$(curl -sL https://raw.githubusercontent.com/circa10a/pumpkin-pi/main/install.sh)"
```
### Go
> Requires Go 1.17+
1. Install [Go](https://golang.org/doc/install)
2. Install [pi-blaster](https://github.com/sarfata/pi-blaster)
3. `go install github.com/circa10a/pumpkin-pi@latest`
4. `pumpkin-pi`
