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 ...

The creative adventures with ATtiny series microcontroller are awesome if you know how to play them. ATtinys — especially the ATtiny85s — are all around us, and by using one, we can shrink the size of ...

Most projects are built on abstractions. After all, few of us can create our own wire, our own transistors, or our own integrated circuits. A few months ago, [Julian Ilett] found a problem using the ...

Here’s an Arduino library that will let you drive a very large number of LEDs. [Elco Jacobs], an electrical engineering student, is the author of the library. He has a work-study job that has him ...

I have been discussing control algorithms for a power supply and idly looking for some easy hardware on which to try the technique – hardware small enough to build into a prototype. See also: An AVR ...

Capable of operating as a position, velocity, or force/torque mode amplifier and controller, the VCA 100 module is designed for use with the company’s linear and rotary voice-coil actuators. The ...
