8x8 rgb led matrix effects

so this is my second arduino project, waiting to be put onto a nice pcb. this is not the sparkfun matrix, but one from china. all the pwm is done on the arduino with an ISR.

HI!! i want one!! Where can i buy thisone? ebay? thank you!

@ctwkkk: I don't make these anymore. BUT nowadays you can get a much brighter unit from others. Google for 'colorduino'. You will need to be familiar with programming in C and feel comfortable with microcontrollers.

How do you do PWM with the shift registers?

[zupnikal]

@FutureInventions: by updating the data very very fast. Today you can easily do it with a library called 'ShiftPWM'.

Hi, did you transistors for driving the LEDs? How many? How did you configure them? Thank you

[zupnikal]

@mattYYYz: No I didn't :-) This is an el-cheapo version using shift registers only. All info is on my blog. And the link to that is on my channel page.

@bigvato01: I don't care... for me this is just a rainbow.
