# alarm-clock
## Device Setup
I'm using a Pi Zero W.
Setup SSH - https://desertbot.io/blog/headless-pi-zero-w-wifi-setup-windows
VS Code over SSH - https://github.com/SchoofsKelvin/vscode-sshfs
Installing Node - https://www.thepolyglotdeveloper.com/2018/03/install-nodejs-raspberry-pi-zero-w-nodesource/
```
> curl -o node-v10.9.0-linux-armv6l.tar.gz https://nodejs.org/dist/v10.9.0/node-v10.9.0-linux-armv6l.tar.gz
> tar -xzf node-v10.9.0-linux-armv6l.tar.gz
> sudo cp -r node-v10.9.0-linux-armv6l/* /usr/local
```
Speaker setup: https://www.lucadentella.it/en/2017/04/26/raspberry-pi-zero-audio-output-via-i2s/
Alarm service definition:
```
[Unit]
Description=Alarm Clock
After=network.target

[Service]
Type=simple
Restart=always
RestartSec=3
ExecStart=/usr/bin/env node /home/pi/lights/server.js

`/home/pi/lights` is wherever you cloned this repo. `lights` is just a holdover on my device from when I was experimenting with the display.
