[Rick Osgood] wanted to build a color sensor that could be held up to any object to get RGB color values. He originally started with a photoresistor and a few LEDs, but couldn’t get that to work ...

But then he went further by modified his galvo scanner to accept the RGB laser; requiring a custom circuit board and new software, both available on his site. The original is in Polish ...

Study sensor signal noise and apply proper hardware techniques to reduce it to acceptable levels. In module 1 you will learn how to specify and use temperature sensors in an embedded circuit. First, ...

True color sensors are based on one of the color models, most commonly the RGB model (red, green, blue). A large percentage of the visible spectrum can be created using these three primary colors.

A Blynk console dashboard for the "Smart AC Meter," was created for the Power Supply Company. The dashboard is online and ...

Sensor chips are dies incorporating semiconductor circuit elements that are used to convert changes to some physical parameter to an electrical signal. Like other semiconductors, a sensor chip can be ...

Following are the conversion formulas from RGB to YUV and from YUV to RGB. See YUV and color space conversion. From RGB to YUV Y = 0.299R + 0.587G + 0.114B U = 0.492 (B-Y) V = 0.877 (R-Y ...

Stars from high-profile entries like “Baby Reindeer,” “Fargo,” “True Detective: Night Country” and more are in the running for this year’s Emmy race in best limited series… ...

With dedicated macro keys, a detachable wrist rest and easy-to-use software, the Corsair K55 RGB Pro is a good membrane keyboard for typing. It also costs just $59. However, all of its goodness is ...
