5 Watt LED Driver Circuit (SMPS)
This 5 Watt LED Driver Circuit (SMPS) shows how to make power supply using wall plug to turn ON bright LEDs. Also, it supports white LEDs but it works with blue, green, red, yellow and even UV light What is a 5 Watt LED Driver Circuit: A 5 Watt LED Driver Circuit powers a 5-watt […]
SMPS Halogen Lamp Circuit
An SMPS halogen lamp circuit mostly needs a transformer to work and in this post we explain a new type of transformer using a switching power supply. Also, the circuit is simpler than old transformers and it can work with other bulbs too but only if they do not use RF (radio waves), furthermore, this […]
Simple LED Fading Circuit using IC 555
Simple LED Fading Circuit using IC 555 is small project for LED light which are very cool and save power, as this LED light goes bright and then goes dim slowly. In this project, we have used 555 IC chip and few other circuit parts which are very easy to make. Circuit Diagram: Parts List: […]
Automatic Street Light Circuit using LDR
In this guide, we show how to use an LDR and a relay to make an Automatic Street Light Circuit. Nowadays, many place uses LED street lights that turn on by itself, because people want to save energy! Therefore, to save power these lights use LDR sensor to know when dark come. Also, this post […]
