How did you get the LED's to dim around 0:25?

[RobbeOfficial]

@sbonkosky its basically some sort of PWM (turn them on and off quickly)

[sbonkosky]

@RobbeOfficial Ohhhh, forgot that those pins are PWM pins as well. Awesome, thanks.

[RobbeOfficial]

@sbonkosky the PWM of the arduino is not used. it's done in software (check the code if you are interested)

[sbonkosky]

@RobbeOfficial i see what your doing there, but how come you chose to do it that way instead of using the PWM functionality of the board?

[RobbeOfficial]

@sbonkosky well i dont remember ... but i do remember is that i did it for some reason :)

post a link to the scheme. NICE!

[RobbeOfficial]

@amaralgustavo there is no scheme .. it's a matrix of 3 layers and 9 "columns". all cathodes of each layer are connected as well as all anodes of each column. wire these 3+9 = 12 connections to your arduino and you're done.

you can find details and the code here:
