very basic 3x3x3 led cube controlled by arduino

a very very basic led cube controlled by an arduino duemilanove. it basically only consists of the leds, some wires and the arduino of course. so it's very easy to build.

note: i also added 3 resistors which turned out to be unnecessary.

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 :)

el pwm no entendi esta el asemmbler o codigo c me puedes pasar el pwm porfavor

@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:

post a link to the scheme. NICE!
