When multiple PWM converters are connected in series (or in parallel) in a power electronics circuit, it is appropriate to run all converters at the same frequency but with certain phase shift among ...

If your Arduino runs out of I/O lines, you can always add one of the several I/O expander chips that takes a serial interface to set its several pins. Or perhaps you could buy something like an ...

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 ...

From your very first blinking LED to dazzling multi-color sequences, Arduino makes it easy to bring light to life. With just a board, a few LEDs, and some code, you can experiment with patterns, ...

This little LED rig fades in time to music. The hardware itself is quite simple, some LEDs connected to the PWM pins of an Arduino. But the signal processing is happening on a computer using a Python ...
