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 ...

This library is used to communicate with the I2C DS1682 from an Arduino. The DS1682 is an elapsed time monitor with an internal calibrated clock. So there is no external clock needed. The device also ...

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 ...

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...

The Modulino Hub, Extender, and Motors boards simplify I2C expansion, long-cable communication, and protected motor control for modular embedded projects. How the Modulino Hub isolates duplicate I2C ...

Programmable logic controllers are widely used in industrial automation systems to control machinery, monitor sensors, and manage manufacturing operations. Although PLCs provide reliable machine ...
