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 […]

Sound Activated LED Lamp Circuit
A highly sensitive sound activated LED lamp circuit can be built using just a few transistors and resistors. The circuit is actually a high gain MIC amplifier circuit which amplifies the external sound hitting the MIC. The amplified signal is then used to momentarily illuminate a bunch of LEDs. What does the Circuit do? Basically, […]
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 […]
Convert any Existing AC Lamp into Timer Controlled Lamp
The proposed push button timer circuit module can be directly integrated with any existing switch contacts of a lamp and enable the lamp to be converted into a timer controlled lamp. A common problem arises whenever one wants to replace a mains AC lamp controlled by a switch with a timer or a time switch. […]
220 V Slow Fade Bedside Lamp Circuit
The operating principle of this children’s night light is to gradually familiarize the child with darkness by gradually reducing the brightness of their bedside lamp. The room’s brightness will slowly fade away and completely extinguish after a duration ranging approximately between twenty minutes and 5 to 7 hours. This duration can be adjusted from week […]
LED Night Lamp with Dimmer Circuit
In this post I have explained a simple plug-in type night lamp circuit with delayed switch OFF and dimming facilities. The entire circuit is built using a transformerless power supply which ensures that the unit is very compact and can be plugged into any existing 220V mains AC socket. Circuit Description The electronic schematic of […]
