What is duty cycle? Duty cycle is defined by the percentage of high voltage duration in a complete digital pulse. If the duty cycle is 50%, then it will remain on for exact half the duration of the ...

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 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 ...

[Dane] sent in his sweet AVR hack. He used the PWM output to play pre-recorded audio output. It’s not very high quality, but it could be useful for adding low cost audio feedback to your projects.
