Prerequisites:

• Node-RED
• npm packages:
  • node-red-dashboard
• Mosquitto

Usage

Setup Raspberry Pi:

1. Start mosquitto broker (Should run automatically as a service after first start)
2. Copy nodered_flow.json as your flow (usually in ~/.node-red folder)
3. Configure the network to use the static local IP address specified in the arduino sketch (192.168.0.101)
4. Setup the wireless card to connect automatically to the local WLAN
5. Either configure node-red to start automatically after boot, or start it manually through ssh. Remember to start it with the correct sketch name (e.g. $ node-red nodered_flow.json)

Setup Feather:

1. Add Feather Huzzah ESP8266 to Arduino IDE (board manager URL)
2. Get Adafruit Motor Shield V2 and PubSubClient Arduiono IDE libraries.
3. Configure MQTT broker IP, WiFi, and motor port in sketch.ino.
4. Flash the code on to the board
