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 ...

Looking for a fun and easy way to add a bit more interaction to your LED-laden projects? Why not turn them into proximity sensing LEDs? Our hacker, [Will], is just getting into designing his own PCBs.

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 ...

To match the brightness and color of multiple LEDs in RGB applications you should drive all LEDs with a constant current. However, some of these driver ICs require the complication of microprocessor ...
