Want a fast PWM quickly? – consider 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 ...

If you do not believe that test it yourself quickly through an Arduino and a PWM example sketch. You can clearly see a big brightness change between analogWrite (x,1) and analogWrite (x,2), but can’t ...

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… ...
