Description

This is a schematic for the notifications buzzer I've created in the video below.

Realtime Event Notifications Using NodeMCU (Arduino), Google Firebase and Laravel

In this video I've created a device that can notify in real time about events that happen on a website. The project uses NodeMCU board and a buzzer to produce sound as alert. The board is programmed with the Arduino software and it uses Firebase Realtime Database to store the events count. Those events are created via Laravel application but they can as well be created by a simple HTML/Javascript, iOS or Android application. The entire code is available on my GitHub page:
