Finally, my Rainbowduino arrived trough my German reseller
So now i am eager to let it do its work.
I have some questions:
I am trying to solder an external RGB 8 x 8 Led matrix out of RGB-Leds, according to the wiring of the “small one” that you just plug onto the Rainbow.
Will this, at first, be possible at all if i stick exactly to the wiring provided in http://www.seeedstudio.com/depot/datasheet/2088RGBMatrix.pdf? I know that it takes a lot of solder-patience
Will i need resistors before every LED Colour channel, or does the Rainbowduino provide exact output?
I saw that the “small RGB-Matrix” does not need any resistors, and the wiring diagram does not show any also.
Thanks for your answers in advance
