LED dot-matrix display is a good medium of displaying information in terms of text or image. More interestingly, texts or images displayed can be made animated instead static in place only. Some related applications are displaying advertisements, time, price of product and scoring.
Pinguino is an easy-to-make Arduino-like board based on 8-bit (PIC18Fx550, PIC18Fx5K50, PIC18Fx6J50 and PIC18Fx7J53 family) and 32-bit (PIC32MX Mips family) microcontrollers. In this tutorial, users will be guided to turn a SK40C board with PIC18F4550 microchip into a Pinguino board and program it for LED blinking.
