Medical Store LED Cross Sign Circuit [Plus Sign]
In this post I have explained how to make an interesting yet simple running LED cross sign or plus sign module for displaying in front of medical stores. Nowadays, it is very common to witness illuminated flashing, chasing LED cross signs in front of medical stores, which work like an advertisement board for attracting the […]
How to Design Simple LED Driver Circuits
In this article I have explained how to design your own customized, simple LED driver circuits at home. We will learn how to calculate specific LED configurations for applying the LEDs with appropriate LED driver power supplies. In these driver power supplies I have explained two concepts one by using SMPS boards and the other […]
