Kumusta!

Which uni are you attending?

It seems like you need a lot of help. Have you seen what kits are available?

I suggest searching the web for something you can copy. Keep it very simple.

I am NO expert but I think you need something like this;


PC ---------->micro-controller------------->led matrix driver------>led matrix

PC to micro-controller could be USB or serial.

What's the name of the 'big' electronics supplier in Manila? They had a store in Mega-mall and a big store in Quiapo?

Ask Zuisti. He is an expert in Matrix Display Projects.

You can use MAX7219 in SPI to control one or many 8x8 LED matrix.
