led

Hi, im curious how to handle ,lets say 20-30, LEDs that could draw max 60mA each on USB device. As i know usb port could deliver about 0.5A and those used in full(white color) draw around 1.2A+ ... This question is about power not how to connect them. What is the trick to use them lets say all...

I'm trying to design an LED driver that takes a ground as ON, performs a logical NOT on it, and sends it into an N Channel MOSFET. The MOSFET will give ground to a color channel on an LED strip. LED Strip Driver-schematic.pdf I believe I have taken care of everything, but to be honest, this is...

I'm in the process of designing an mono-color LED matrix that is basically in the shape of a horseshoe/rainbow, with the ability to control individual LEDs, preferably with an Arduino, as I'm familiar with them. As of now, due to space constraints, I'm using 0603 LEDs, but that eliminates the...
