Abstract

In the age of semiconductor domination, LED light sources became cheap and popular. Authors of the project, focused on application of LED in graphic displays. Main target of designed and manufactured system was its versatility. It was obtained by projecting similar segments that one can merge at will. This allows us to build simple clock with one segment or sophisticated display for advertisements. LED matrices are driven by 8-bit shift registers, which are controlled by AVR micro-controllers. Micro-controller application allows connecting extension modules such as digital thermometer, easily. Communication between micro-controller and personal computer is over RS232 interface. This provides possibility to drive display over TCP/IP protocol
