In this post, two LED blinking circuits are given below. First one is dancing bi-color LEDs (two different color LEDs) where the two color LED will run in sequence. In the second circuit, we will ...

Discover how to build a simple wireless power transfer system at home using readily available components like enameled copper ...

Digi-Key Technologies has developed a diagramming tool that includes a comprehensive electronic symbol library and an integrated Digi-Key component catalog that allows for a wide range of circuit ...

Lighting a string of LEDs at a constant brightness requires driving it with a regulated current. A boost converter is commonly used to step up the voltage to a level high enough to bias the LEDs on ...

[Peter] needed to drive a high power LED for his microscope. Rather than pick up a commercial LED driver, he built a simple constant current LED driver and fan control. We’ve featured [Peter’s] ...
