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 ...

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 ...

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 ...

Having advocated Arduinos for prototype PWM signal generation, I have just discovered a subtlety that might trip up the unwary (amongst which I count myself). The original idea was not to use Arduino ...

I was recently working on an experiment for a new design and was using a function generator. Although new function generators have pretty good frequency tolerance specs, I needed something with more ...

According to Tom's Hardware, the railroad equipment came from T-gauge, a hobby company specializing in small-scale components. For now, the conductor is using an Arduino on ...
