Diodes are one of the most important parts of any electronics project, and if you don't understand how they work you'll destroy any electronics project you work on. Thankfully, Adafruit has a video ...

We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop? Analog VOM’s attempt to measure resistance of ...

This video explains how semiconductors work and how their electrical properties are controlled using band gaps and doping.

This video explains how LEDs (Light Emitting Diodes) function and why they are widely used in modern lighting and electronic displays. LEDs convert electrical energy into light through the movement of ...

This Design Idea illustrates a way to make use of MOSFETs’ parasitic body diodes in a power circuit that can be used in UPS and energy-recovery (e.g., regenerative braking) designs. The circuit can ...
