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 ...

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 ...

I know very little about electronics, but if you give me a schematic and a pile of parts, I can more-or-less assemble them correctly.<br><br>I am trying to build a simple circuit to simulate the ...

Digi-Key prevents a video clip discussing the steps on how to assign parts to components in Scheme-it. In this video, a simple LED circuit is used to show how to assign actual part numbers for the LED ...

If you’ve worked on a project with small LEDs, you know the frustration of determining their polarity. This ingenious LED Probe from [David] packs a lot of useful features into a simple, ...

The creative new approach could lead to more energy-efficient machine-learning hardware. On a table in his lab at the University of Pennsylvania, physicist Sam Dillavou has connected an array of ...

[Boylei] shows that those little LED filament strips make great freeze-frame blaster shots in a space battle diorama. That’s neat and all, but what we really want to highlight is a simple tip [Boylei] ...
