The project shown here is a cheap 60W LED dimmer for 12V LEDs/12V LED strips. The circuit is based on the very popular, versatile, and low-cost 555 timer IC, NE555 IC generates a PWM signal and IRF540 MOSFET works as output driver for the LEDs. In this circuit the 555 IC used in an...

OSRAM Opto Semiconductors DURIS® E 2835 Color LEDs feature excellent color rendering and supreme efficacy in a 2.8 x 3.5mm² PCT package. These color LEDs offer a 120° beam angle and 2kV ESD withstand voltage. The DURIS® E 2835 color LEDs are available in red, green, blue, deep...

Now, from my writing experience here at eLab, I have dealt with some funny and interesting concepts, but nothing quite like what I am about to show you. But bear with me here, aside from the questionably looking electronics you are about to glance, there might be something useful to...

OSRAM Opto Semiconductors OSIRE® E3323 RGB LEDs offer individually addressable LED chips for maximum flexibility in terms of color point, driver selection, and interconnection. These LEDs provide an integrated Dot Matrix Code (DMC) that provides the measurement data of luminous...

Power analysis is a technique to probe the inner workings of an integrated circuit by measuring changes in the supply current. Tim writes: Whenever a logic gate switches, it will cause a tiny current spike that can be measured externally. By inspecting the temporal variation,...

This project is built for fun-loving users to create a 24 LED bar-graph for light effects that can be driven using Arduino or another microcontroller. The project consists of 74HC595 x 3 chips, and 24 LEDs of Red, Green, Blue, and Yellow colors. The project helps the user to experiment...

The Taiwan Semiconductor TSCR4 family of linear CMOS LED driver ICs offers a drop-in replacement for legacy bipolar drivers with much improved performance . These constant current drivers provide stable LED current over a wide range of conditions including source voltage variations and...
