I bought a couple of 3W power leds on Ebay recently. These 3 watt power leds have a forward voltage of 3,4V and need 700mA current to shine at their maximum rating. A led is a semiconductor and needs current limiting to make it work. With small leds you just put a small resistor in […]

I didn’t have much trouble putting sketches on the chip when I put it on a breadboard. While searching for information on how to accomplish this I read that putting […]
