Hello guys, today I am going to tell you an easy way to make an Automatic night light circuit(automation) without using any micro-controllers or development board. With a circuit diagram as well as a simulation video of working of this project. This is possible with a simple analog circuitry using some active components as well […]
Transformerless Power supply 220v ac-20v
[powering led with 220 v AC] Have you wondered how Bulbs/lights work directly on mains 220v AC input without a stepdown transformer to lower voltage? The circuit discussed in this article shows and explains how to power LEDs from 220v ac source without using a stepdown transformer. The same concept is used in our modern […]
