This code receive a massage from a Telegram Bot and respond of a specific requests. One of this command can display ( /disp ) a msg on the Matrix display.

When the device is new for the network, the BOT becomes a WiFi station. You can connect to the wifi station and enter the credentials of your network.

The device have a deep sleep mode ( the pink wired in the schematic ) that guarantee a low power consuming during the WiFi station mode.

I added an RFID Tag inside the case with the link to a chat with the BOT.

Library for my project

I used different library for my project:

Telegram bot:

Dot Matrix:

I decide to edit the origin library because i wanted a boolean command that can return to me when the all words are displayed.

This command is:

scrollEnd();  // it return 1 when the word is completely displayed

The library that include this and other command is this.

WiFi manager:

At some point in my project, i decide to drug it outside my home, just for a test.

When i was in the the lab, without my pc, i found this new problem: 

"How can i change the WiFi that connects my device?"

I searched on the internet and i have found this amazing library for doing the WiFi manager job without my pc!
