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 ...

When we hear about a brain controlled Arduino project we immediately think about a coding nightmare. As always, the simple hacks are the best hacks. [Joel] and [Akshay] used hardware from a kid&#82… ...

In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...

But this Arduino device can be programmed to control a whole host of devices: As long as it has an infrared interface, chances are you can get this to work–whether it be a TV, DVD player, VCR ...
