How to create an Usb controlled rgb light that changes colour depending on input from pc? Answered
Im trying to create an led array of 30 leds (10 red, 10 green, 10 blue) that recieve an input from the computer and light up accordingly. E.g. 10 Red, 0 Green, 10 blue to make purple I've found several projects that will light up the leds when the usb is plugged in but id like to control which leds are lit. Is anyone able to draw an circuit diagram for me or suggest anything to help me make this project as i can probably program something to send the output from the computer but its the wiring of the controller etc that im not so good at figuring out.
