Simple Scrolling RGB LED Circuit

A simple RGB (Red, Green, Blue) moving or scrolling LED display can be made using a few 4017 ICs. Let’s learn the procedure in detail. Understanding RGB LED RGB LEDs have become quite popular these days due to its three-in-one color feature, and because these can be driven independently using three distinct supply sources. I … Read moreSimple Scrolling RGB LED Circuit

How Thyristors (SCR) Work – Tutorial

Basically an SCR ( Silicon Controlled Rectifier) which is also known by the name Thyristor works quite like a transistor. What  SCR Stands for The device gets its name (SCR) due to its multi layered semiconductor internal structure which refers to the “silicon” word in the beginning of its name. The second part of the … Read moreHow Thyristors (SCR) Work – Tutorial
