Controlling The 64 Led Rgb Matrix; What Microcontroller Should I Use; Connecting A Panel To An Arduino Uno - Velleman VM207 User Manual

Controlling the 64 LED RGB matrix

What microcontroller should I use?

You can use a lot of microcontrollers or microcontroller platforms to control your panel. But to make things easy
and fast, we are going to explain how you use your panel with a microcontroller platform that is compatible with
the Arduino IDE, like the Uno, Mega, Teensy and many others.
If you do not want to use any of these platforms, you will have to dive a bit deeper and learn how to create
the data stream that is needed to control a bunch of WS2812 LEDs. You can find the needed information here:
WS2812 DATASHEET.

Connecting a panel to an Arduino Uno

Follow the drawing below to connect a panel to an Arduino Uno. At the moment we use pin 6 as the data output
but this can be changed in the code later. Supply the Arduino with power as well as the VM207 and connect the
grounds together.

ATTENTION
Do not use the 5 V from the Arduino to power one or more panels. These panels draw to much current for the
regulator on the Arduino. If you do this you could break your Arduino board.
