Help Controlling LEDS
I am new to Microcontrollers and wanted to become more familiar with it so that I can do big projects .... I wanted to know how to control a number of LEDs more than Output ports on Microcontroller ..
For example ,
Microcontroller has 32 I/O pins and i want to control 40 leds , how can I do it .?
I want to know more and more about controlling LEDs like 6x20 led matrix display for whole word display with a software on computer or keypad attached to circuit board .
I am using PIC16f877A and I have made a development board for it and also have a parallel port programmer .
Anyways thanks for reading .
