4 pin (RGB-5V) with Arduino over analog pins?
I'm currently trying to figure out how to power my LED strip. The whole thing should be controllable via three analog pins.
I got a breadboard power supply because the power from the PC/USB definitely won't be enough. But now I'm confused about how to connect it without risking overloading my Arduino, since I don't have a data pin or anything. As I understand it, there are three separate circuits that all run through the 5V pin.
In the current case, there are only 12 RGB LEDs, but there will probably be more in the future. But even 12 LEDs are above the recommended 200mA.
I have already built some circuits with multiple RGB LEDs, but all are controlled directly via the Arduino pins (max 3 LEDs in parallel).

get you a mosfet driver module for your arduino.. load on the arduino switch you don't.
The Arduino has no analog pins (for output). He has analogue inputs, but no outputs.
Maybe you're looking for other LEDs that won't be fired directly with the data lines. eg neo-LEDS. I gained good experiences at the Arduino. That's what Luzi's doing about brightness.

the arduino can provide both analog and digital outputs. is called pwm.
I confused this with pwm output, sorry. Have it now managed to control it via mosfet and currently look for ICs to control several of the led strips as single “pixels”.
