• 3 jumper cables (M-to-M)

How to setup (client only)

1. cd client
2. npm install
3. If not using Arduino, comment out line 29 in index.html
4. npm run dev

How to setup (with Arduino)

1. Setup Arduino:
   1. Place potentiometer on the breadboard
   2. Connect center pin of potentiometer to A2 (it can be any analog port but the code is currently set to port 2)
   3. Connect right pin of potentiometer to 5V
   4. Connect left pin of potentiometer to GND
   5. Connect Arduino to computer
   6. Open Arduino IDE and paste contents of src.ino
   7. Upload contents to Arduino
   8. Make note of the port that the Arduino is on (found in Arduino IDE). You'll need it in a future step
2. cd arduino
3. npm install
4. Create a .env file, create a variable ARDUINO_PORT, and set it to your Arduino's port
5. node app.js
6. Follow client setup steps above
