moon-arrow

Code for johnny-five control of azimuth and altitude servos for moving moon arrow on a schedule

Installation

Hardware: Arduino Uno, 2 continuous servos, jumper cables
On Pi3:
- Install ssh/VNC: https://www.hackster.io/IainIsCreative/setting-up-the-raspberry-pi-and-johnny-five-56d60f
- curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
- sudo apt-get upgrade
- sudo apt-get install -y nodejs
On Windows:
- Install WSL https://www.howtogeek.com/249966/how-to-install-and-use-the-linux-bash-shell-on-windows-10/
- Install Arduino IDE https://www.arduino.cc/en/Main/Software (Windows installer)
Clone this repository, using GUI or commandline: git clone https://github.com/saanobhaai/moon-arrow.git /path/to/repos/moon-arrow/

In WSL or from linux:

sudo npm install johnny-five
sudo npm install node-schedule
sudo npm install suncalc

Attach azimuth and altitude servos to desired pins with 5V power and ground also connected
Plug in Arduino to USB port
Determine port. On a Pi3 this should be /dev/ttyACM0 but may need to do some research depending on model/environment.
On Windows:
- Open Windows Device Manager, note COM port number used by Arduino
- Map Windows COM<N> to WSL /dev/ttyS<N>

  In WSL:
```
sudo chmod 666 /dev/ttyS<N>
stty -F /dev/ttyS<N> sane 57600
```
- Run Arduino IDE serial monitor, verify one-line response from board
Create config for local environment:
- cp /path/to/repo/config.sample.js /path/to/repo/config.js
- adjust constants in config.js as necessary, using port and pin data derived from above
