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 ...

Fancy making a cool looking magnetic levitating lamp? Check out this Arduino Nano-based project that combines a magnet and LEDs. What's that you say? The lamp is not levitating, it's being held up?

[Alex] needed a project for his microcomputer circuits class. He wanted something that would challenge him on both the electronics side of things, as well as the programming side. He ended up ...

Here are the general steps involved in working out the energy balance with LEDs when the juice comes from alternative sources. In most electronic circuits, the expected loads drive the component ...
