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 ...

An automatic toll gate system using Arduino revolutionises traditional toll collection by eliminating manual intervention.

An idea in an earlier blog is to make a pwm interface that can accept 5, 12 and 24V pulse streams. That one uses a bunch of resistors and has three separate inputs. Below that, wise commenter DB ...

The Arduino 101*/Genuino 101* board is the first development board to be powered by Intel® Curie™technology. It counts with the same peripheral list and controllers as the Arduino* UNO board. Sharing ...

…which would take a pulse-width-modulated waveform at any frequency, and produce a signal with exactly the same mark/space ratio, but at a nominated frequency (see ‘Why might this be useful?’ below).
