Welcome to American Libraries’ 2026 Library Design Showcase, our annual celebration of new and renovated libraries across the US and Canada. The word welcome appeared in many of this year’s ...

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 ...

The I2C, standing for I-Squared-C or Inter IC, bus is one of the most useful ways of connecting moderately sophisticated sensors and peripherals to any processor. The only problem is that it can seem ...

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 ...

The Inter-Integrated Circuit (I2C) protocol has been the backbone of short-distance, intra-board communication. However, implementing robust I2C communication is not just about connecting two wires.
