Experiments 5.3: 8x8 LED Dot Matrix Display Tutorial (Red/Green Common Anode) using the Arduino
In this video a 2 Colour (red/green) 8x8 LED Dot Matrix Display circuit is developed that uses three 74HC595 ICs to drive the rows/columns and a darlington transistor array (UDN2981A) to source the current. An Arduino is used to provide the serial data and the source code is presented to show how this was achieved. The display is a common anode ...
