Smart Led Messenger, Connected Displayer




Hi Maker,

Here is a connected object named Smart Led Messenger.

With it, you can display a magnificent scrolling message retrieved from internet !

You can make it yourself with :

Led Matrix 8*8*4 - ~4$

Microcontroller Wemos D1 mini V3 - ~4$

3d printed box - ~1$ (PLA cost)

USB wire (android connector) - ~1$

0,5 v power supply - ~2$

Arduino IDE - free

Step 1: Wiring

You need to solder 5 wires between Wemos D1 mini V3 and led matrix.

//################# DISPLAY CONNECTIONS ################

// LED Matrix Pin -> ESP8266 Pin

// Vcc -> 3v (3V on NodeMCU 3V3 on WEMOS)

// Gnd -> Gnd (G on NodeMCU)

// DIN -> D7 (Same Pin for WEMOS)

// CS -> D4 (Same Pin for WEMOS)

// CLK -> D5 (Same Pin for WEMOS)

Step 2: Program Upload

Install Arduino IDE and configure it in order to be able to upload to Wemos card.

A very good instructables explains how to do that here.

After that download the program here :


And Upload it to Wemos card.

Step 3: First Setup

In order to use your Smart Led Messenger, at first start (only), you need to define Wifi login/password.

Just switch on your Smart Led Messenger and join its own Wifi access point named 'SmartLedMessenger'.

Select your wifi Access Point and set your login/password. They will be stored to the internal memory even if you restart your Smart Led Messenger.

To reset them, just push reset button of Wemos card, and join its own wifi access point to select another wifi access point and define appropriate login/password.

Look your scrolling message and smile !

If you have any questions, just ask and I will do my best to answer you.

If you do not want to do it by yourself, just order to me your smart led messenger for 39$. :)

Many thanks for your attention!

    You can change the message in two ways, directly in http to the box when she is connected to your Wifi network or via an URL where the box gets a string to display.
