Idea

Our project demonstrates the Wireless Display of messages using Wiznet WIZwiki w7500, Max7219 and Smart Phone. It basically connected using the MQTT Protocol.
The MQTT broker will act as a bridge between the Smartphone and Dot Matrix. When a message is sent from the smartphone, the message is sent
to the MQTT broker and the broker will publish the message to the Dot Matrix which is configured with the microcontroller (Wiznet WIZwiki w7500).
The microcontroller sends the data into the dot-matrix using the MAX7219 library built for Wiznet WIZwiki.

INTRODUCTION:

Our project demonstrates the Wireless Display of messages on Dot-matrix using Wiznet WIZwiki w7500, Max7219 and Smart Phone. It basically connected using the MQTT Protocol.

The MQTT broker will act as a bridge between the Smartphone and Dot Matrix. When a message is sent from the smartphone, the message is sent to the MQTT broker and the broker will publish the message to the Dot Matrix which is configured with the microcontroller (Wiznet WIZwiki w7500).

The microcontroller sends the data into the dot-matrix using the MAX7219 library built for Wiznet WIZwiki.
