Arduino Controlled RGB LED Matrix - Test 1

This is the first test of my RGB LED Matrix controlled by an Arduino through 2 x 74HC595N shift registers. One is controlling the rows (Common Anode) and the other the blue columns. The rows are multiplexed one at a time at a high frequency faster than the human eye can perceive to enable the 16 outputs from the 74HC595N's to control the 64 LED's.

Will add another 2 shift registers to control the green and red columns next.

One resister per anode

[timcki]

Just Started playing with the arduino Uno . I am interested in some of your older videos involving the RGB matrix do you have any links to code or schematics that you have done?

[F3rnando666]

one question!.. do you use one resistor per led (in the cathode) or one resistor per color (one for each anode)??.. i`m assuming they are common cathode, if not, well its the other way arround jeje.. if you coud tellme the schematics that would be great!!..5/5
