The LED driver automatically adjusts the output voltage to keep the output current constant and therefore the light output constant. This works with a single LED or with a chain of string of LEDs ...
Normally, when a project calls for addressable LEDs, we just throw a strip of WS2812s and an Arduino together, cobble together some code from the examples in the FastLED library, and call it a day. We ...
LEDs for lighting are found anywhere from DIY IoT modules to commercial lighting applications and the cabins of airplanes. To run properly, these critical lighting devices require a precise balance of ...
An avalanche photodiode (APD) delivers a useful electron-multiplier gain and generally improves signal-to-noise ratio (SNR) in optical communication systems. An APD is similar to a PIN photodiode with ...
The LT3954, a DC/DC converter designed to operate as a constant-current source and constant-voltage regulator with an internal 5A switch, is now available from Linear Technology. June 25, 2013 2 min ...
At first glance, [RobBest]’s constant current source looks old school. The box is somewhat old-fashioned, featuring switches and binding posts. Most importantly, there’s a large analog meter ...
