Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

[mircemk] built a slick-looking LED tester with a couple handy functions built in. Not only can one select a target current to put through an LED, but by providing a target voltage, the system will ...

I had the idea of building this Arduino icicle lights project during the making of the light dimmer circuit and the result can be seen below. Is not a complicated project so it can be done easily by ...

This resource provides clear explanations of how switching regulators work and how voltage boosting is achieved efficiently in practical circuits. A Joule Thief circuit is a small, energy-efficient ...
