SMPS is the acronym of the word Switch Mode Power Supply. The name clearly suggests that the concept has something or entirely to do with pulses or switching of the employed devices. I have explained how SMPS adapters work for converting mains voltage to a lower DC voltage. Advantage of SMPS Topology In SMPS adapters […]

I have compiled a complete list of categories on this website to help you quickly find and navigate the electronic circuits you’re looking for. Let’s get started. Arduino Projects for Engineers In this category I have introduced comprehensive Arduino circuit designs for EEE and BE students. These include detailed explanations, images, and online support, which […]
Security Alarm Circuit using RCWL-0516 Microwave Radar Sensor
This security alarm circuit using RCWL-0516 microwave radar motion sensor will detect any moving thing in the restricted area and turn ON an alarm sound. The RCWL-0516 is basically an advanced motion sensor using microwave radar signals. I have already discussed the working of RCWL-0516 elaborately, which you can read for more details. Circuit Description The […]
Smart Street Lamp Circuit with Motion Sensor
This simple yet highly sophisticated, smart LED street light circuit automatically switches ON a street lamp from low brightness to high brightness whenever it detects a moving object underneath it. This action is initiated only during nighttime, while during daytime the street lamp remains completely shut off. What this Circuit will do This advanced automatic […]
Darkness Activated PIR Lamp Circuit
A very simple darkness activated or night activated PIR lamp circuit project has been explained in the following article. Further in the article we also learn how to upgrade this circuit with an additional emergency lamp facility. This darkness activated PIR lamp will work as I have explained below: It will remain deactivated or disabled […]
High Efficiency Solar Charger Circuits using Switching Regulators
Solar power or electricity from sun light is so abundant that we can afford to waste it or dissipate it in the form heat. This means that we can use large, high power solar panels to charge batteries with lower power without bothering about how much solar energy is being wasted and how much the […]
