Led Matrix Schaltplan. The tricky behind the display is multiplexing and the idea is the same as withe the 8x10 led matrix. Free shipping by amazon.
The led matrix is driven via a high speed multiplex generated by application processor software. Now this time we have 3 shift registers which multiply the number of outputs and save lots of arduino pins. This way you can save a lot of pins on the arduino and keep your program quite simple.
The rgb led consists of three different led s from the name you can guess that these led s are red green and blue.
We can obtain many other colors by mixing up these colors. It is basically a way to split information in to little peaces and send it one by one. The arduino has a analog write function which will help us in obtaining different colors for arduino rgb led. Attach the 8 pin headers to feed power to the leds be sure to place a 200 ohm resistor in line with each positive power lead.
