Halo, I want to be able to color a glass plate using a lot off RGB Leds, for now it is okay if the entire plate is the same color. (In the end it should be wireless using the Xbee, but lets start with the basics)
I can make 1 LED dim and change color, but I need more light than 1 LED.
What kind off LEDs should I use? I read that it is not possible to connect thos 4 Pins RGB LEDs (with commen cathode) in series, so is it better to get a bunch off Red, Green and Blue ones?
I know my Arduino can only power so many LEDs, so how do I go arround and connect them together using a second power source?
An idea I was thinking off PWM-ing a transistor for this, would it work? what transistor would you recommend me?
Isn't PWM-ing a pin and recieving DATA from the PC interfering with eachother? perhaps different ways, like using the 555.
Any other tips/hint are also welcome, thank you for your time, I am a newbee, so keep it simple.
