Here is the list of best LED based projects along with the circuit diagram, working and applications. LED – Light Emitting Diode. We are all very well know that LEDs are now playing vital role in many ...

In this article I will add some simple Arduino LED projects starting with basic ones like how to turn on an LED, blinking, and more. Every step will have the code, the schematic, photos of the project ...

LED-driver circuits can be dimmed by applying a variable duty cycle (pulse-width modulation, or PWM) to the LED. PWM exploits LED behavior: At higher current levels, the LED’s light output is higher ...

This simple 4093-based audio peak detector from December 2004 monitors music and turns on a small light when the sound gets ...

Businesses, municipalities, and universities from coast to coast have embraced the long-term benefits of LED lighting. However, many organizations miss out on additional ...
