Microcontroller port pins can typically be driven either high or low, or else be put into an "input" or high-impedance state. This circuit uses the three states to drive two separate LEDs with one ...

You’ve probably heard of light-emitting diodes, a type of energy-efficient light. While they’re good for practical reasons—say, illuminating a room or a passageway—they can also add a little bling to ...

Learn how a bootstrapped buck-boost converter can be used to extend the battery life of a low-cost, portable LED lamp.

LED bulbs may malfunction due to design flaws and excessive heat accumulation. When one diode burns out, the entire bulb may cease to operate. By locating and bypassing the defective diode, it's ...

Tagging wildlife is never straightforward in the best of times, but it becomes a great deal more complicated when you’re trying to track flying insects. Instead of trying to use a sensor package, ...
