In this post I will show how to construct LED strip controller circuit using Arduino, which can turn ON/OFF and decrease/increase brightness of LEDs using ordinary IR (Infrared) remote. What is LED Strip Light? (For noobs) If you are not familiar with LED strip lights, let’s understand what it is. LED strips (sometimes called as […]

Ceiling LED Lamp Driver Circuit
Nowadays the CFL and fluorescent lamps are almost completely replaced with LED lamps, which are mostly in the form of circular or square shaped flat ceiling mounted LED lamps. These lamps beautifully merge with the flat ceiling surface of our homes, offices or shops providing an aesthetic look for the lights, along with a high […]
LED Oscilloscope Circuit
The simple LED oscilloscope circuit I have explained in this article can be used for analyzing low frequency waveform through a 10 x 10 LED matrix display. Due to the involvement of only 100 LEDs in the display board, the resolution is low, and the waveform display clarity is not so impressive. Yet, this LED […]
Blinking LED Circuit using LDR and Resistors
This is perhaps the most simplest looking LED flasher that does not depend on any semiconductor. This LED blinker circuit utilizes ordinary passive components like a few resistors, a capacitor and an LDR. Meaning, this LED flasher does not depend on transistors or ICs to create the blinking effect. Circuit Description The LED-LDR combination is […]
Simple 4 Watt LED Driver Circuit Using IC 338
This 4 watt LED driver is a device that will illuminate a 4 watt LED safely through a constant current circuit using the IC LM338. The IC LM338 as we know is a highly versatile device when it comes to controlling voltages and current levels. Circuit Configuration In the present design, the device is configured […]
Simple Hi Efficiency LED Torch Circuit
A simple LED torch circuit that would light up 3 white LEDs from a 6 volt supply and would make your battery last forever is described here. A useful voltage doubler circuit is incorporated here to make a highly efficient circuit using just a handful of components. Introduction Learn more how to build it. White […]
