- connect LCD pins to the Quadrant board Arduino pins.
- connect 8×8 matrix pins to the Quadrant board Arduino pins.
- create a google Firebase project.
- download Quadrant IoT Example from Projects.
- then change ssid,wifi password and Firebase information on both Arduino and NODE MCU firmware files.
- now upload Arduino firmware to Arduino board and NODEMCU firmware to NODEMCU board.
- then connect NODEMCU [TX] pin to Arduino’s [RX] pin.
- now you can change the Firebase data directly or use the java application to control the example.
