Quick Start

1. Setup The ESP8266
   • Download Arduino IDE: https://www.arduino.cc/en/Main/Software
   • Open Arduino IDE and click: File -> Preferences -> Additional Boards Manager --> Paste this link: https://arduino.esp8266.com/stable/package_esp8266com_index.json
   • Setup the board: Go to Tools -> Board -> Board Manager -> search ESP8266 Community, then click install
   • Select the ESP8266 board: Tools -> Board -> NodeMCU 1.0 (ESP12E Module)
   • Select the PORT: Tools -> PORT -> USB0 (or anything that works)
   • Upload the Code: Sketch -> Upload (There should be no error. If there is, it is mostly about user permissions. Message me if you can't go through this.)
2. Upload the code dofii.ino
3. Find the IP Address from the Arduino IDE Serial Monitor.
4. Copy and paste the IP Address in the browser and start from there
