Control 4 Matrix 8x32 - Arduino - MAX7219

About: Electronics Hardware Designer RF & Antennas - PCBs & Manufacture

Este proyecto es uno de los mas simples de llevar a cabo ya que no requiere de muchas conexiones y con solo cargar el firmware en el Arduino podremos controlar la Matriz de 8x32, podremos escribir mensajes con desplazamiento Scroll de forma indeterminada (para que quede pasando continuamente a modo propaganda) también podremos enviarle mensajes a demanda para que la misma pueda mostrar estos.El proyecto requiere de un Arduino (puede ser cualquiera, yo he implementado el UNO porque lo tenia aquí, pero puede ser cualquier otro) y matrices con controlador MAX7219, en mi caso he utilizado un modulo de 4 matrices interconectadas, pero es posible utilizar mas matrices o menos.En este proyecto los mensajes podemos enviarlos por puerto serie del mismo arduino, pero podríamos emplear un modulo bluetooth serial, y de esta manera no necesitamos la PC conectada, solo un terminal bluetooth.

Step 1: Control 4 Matrix 8x8 With Arduino and MAX7219

This project is one of the simplest to carry out since it does not require many connections and just by loading the firmware on the Arduino we can control the 8x32 Matrix, we can write Scroll scroll messages in an indeterminate way (so that it is happening to you continuously) to propaganda mode) we can also add messages to the demand so that people can see them.

The project requires an Arduino (it can be anybody, that implemented the ONE because it had it here, but it could be another one) and the matrices with the MAX7219 controller, in my case a module of 4 interconnected matrices was used, but it is possible to use more matrices or less. In this project, the messages can be sent by serial port of the same arduino, but with a serial bluetooth module, and in this way we do not need the connected PC, only a bluetooth terminal.

The program uses the library of Adafruit GFX and that of MAX7219, we must download them, I will leave them on my GitHub site for greater ease. Then the rest comes by default in ArduinoIDE (like the Puerto SPI "Wire.h").
