In this tutorial, we will learn how to make a Web Controlled Smart Notice Board with ESP8266 & Dot Matrix LED Display.
The traditional methods of writing the notice on paper, and having a person deliver the information to the respective groups, or having him paste the notice on the notice board, are prone to errors. The person delivering could deliver it to the wrong group, or tamper with the information being sent, etc.
With the electronics industry moving at a fast pace, we are able to solve many such problems with digital replacements. Our project, Smart Notice Board, aims at eliminating the use of paper in offices, schools & colleges, and other institutions. It also minimizes the risk of errors, by replacing paper with Dot Matrix LED displays.
In our project, the ESP8266 WiFi Module can be interfaced with an 8-in-1 MAX7219 Dot Matrix LED Display. The ESP8266 connects to a WiFi Network and generates a Web page. We can access the web page using the local IP Address of NodeMCU ESP8266. Using the Web Dashboard, we can send any message and display it on Dot Matrix LED Display.

Wow i tried it and it worked 100% thank you brother
Cool project: Quick question how did you connect the 2x 8x32 together ❓
And possible to make the schematic in "Fritzing" ❓
How you can access on web.
How to deploy, and where
Great Work bro. Very useful and this version is better.
Nice project 👍
thankyou for the help . can you please tell me hoe to increase the intensity of the led lights because it is low in my matrix display
The voltage regulator isn't needed, NodeMCU have one. Just supply 5v to Vin on the NodeMCU and the Vcc on MAX7219.
How..?
Very nice, but what happens if you remove power? Will it remember everything, including your scrolling message when powered back on? Let's say you want to have this running for a few hours every day, with the same message, maybe only change it every few weeks, and you have it plugged into a timer or an alexa plug so it comes on for a few hours every day. Will you have to re-enter a message/text every time? Would be great if it remembered everything.
When u remove power everything is erased.
@@HowtoElectronics Thanks for prompt reply.
good video, Can I run the system on an ESP32 with the same code?
Nice project... Finally i understand We can control from anywhere using mobile wi fi network and my doubt is nodemcu also required wi fi connection means internet connection always?
Bro ppz teel me which language is used to create the web site and is there any need of Arduino ide plz 😢😢😢
How to use 8x32 neopixel display for this project
Can you make it ?
Your next video
Hi, is it possible to use the same method with ESP32S?
And I wat to use only 4 in 1 dot matrix not 8. Please reply me
Bro you can use 4 In 1 dot matrix but not esp32s

Hii mam
You have a ppt??
I have doubt , that we can control and change from anywhere ? please reply
Its based on webserver, so you will need a local network and can control from your home only.
Awesome
👍👍👍
great video
Nice 🎉
Super
Nice
Medam i want show time
