This library is to use an HC4067 multiplexer by means of a PCF8574 (I2C 8 channel IO). The HC4067 allows e.g one analog port read up to 16 different analog channels, or one digital port to read the ...

A new fully featured Arduino development board has been created called the Prestissimo Uno+ which is now available to back via Kickstarter with earlybird pledges available from just $20, AUS$28 or ...

Assume that you are moving towards a complex microcontroller project bundled with blinkers, beepers, and a display panel. To link a standard 16×2 LCD directly with the microcontroller, for instance ...

[Johngineer] found himself in need of an I2C sniffer, but didn’t have one available. Necessity is the mother of invention, so he put together this I2C sniffer sketch for Arduino. The arduino will ...
