Project Description:
********************
In today’s episode you will learn how to make an IoT “Internet of Things” based Notice Board using Nodemcu ESP8266 Wifi Module, Max7219 dot Matrix 8x8 LED modules and Blynk application… The scrolling text message on the 8x8 LED Matrix can be updated at any time from anywhere around the world using the Blynk application… The scrolling speed of the text message can be controlled using a variable resistor or a Potentiometer… This is version 3 of the 8x8 scrolling message which is entirely based on my previous two tutorials.

Version1 is based on the computer-controlled scrolling text… while version2 is based on the Bluetooth controlled 8x8 LED Matrix Scrolling text display system. So, I highly recommend first watch my previous two tutorials and then you can resume from here.

Without any further delay, let’s get started!!!
