Arduino TA07-11 5x7 Dot Matrix Display
Table of contents
In this Example I am using a Kingbright TA07-11 Dot Matrix LED Display using an Arduino as controller.
The code is mostly based on the DirectDriveLEDMatrix example on the Arduino playground website.
The next step will be to use a LED driver IC for keeping the usage of Arduino ouputs low.
The five Transistors are for regulating the voltage on the columns of the Display. In this circuit all LED's are getting the same voltage power of 5V.
The code looks very ugly at the moment, but I will clean it up. It is a dirty written prototype... ;)
