Controlling LEDs is really quite simple. As you know, they need to be current limited which is as easy as applying Ohm’s law to your given set of values. To make things even more even there’s a slew ...

This is an easy tutorial showing how you can control the brightness of an LED or adjust the speed of a DC fan using Arduino Board, a small BC547 transistor and a potentiometer. In my example the whole ...

NEW DELHI: LED drivers are fluorescent lamps or transformers for low voltage bulbs. They provide the correct amount of power to LED bulbs to function without any problem. However, we have already ...

Light emitting diodes (LEDs) are low-voltage light sources that require a constant DC voltage or current to operate optimally. Because they operate on a low-voltage DC power supply, they easily adapt ...

A miniaturized driver manages red, green, blue, and white LEDs for maximum impact with minimal system CPU burden.
