Simple LED Fading Circuit using IC 555
LEDs are super cool and efficient light sources that are everywhere these days. This post will show you how to make an LED light that slowly fades in and out. It might sound fancy but only few circuits parts and a classic chip called a 555 IC is needed. What is a LED Fading Circuit […]
Automatic Street Light Circuit using LDR
In this post we learn how to build an automatic street light circuit using LDR and relay. Saving energy is important, so many places are using special street lights with LEDs that turn on by themselves! These lights sense darkness using a light sensor called an LDR which helps save power. This article explains how […]
