Veteran-led Kupros has figured out a way to dramatically speed up the prototyping process for 3D-printed electronics.

A fundamental difficulty of working with nanoparticles is that your objects of study are too small for an optical microscope to resolve, and thus measuring their size can be quite a challenge. Of ...

This IO expander plugs into an Arduino Uno to add more controllable pins. It can be used for instance to interact with TTL circuits. One configuration can be 24 bits output and 8 bit bi-directional.

Since ESP32_IO_Expander depends on the esp-lib-utils library which implements the logging, checking, and memory functions, to configure it when using Arduino, please refer to the instructions.

ESP32 controllers are well-like solutions used in thousands of IoT, smart home, and other remote control projects. The ESP32 has also a good I2S interface, which can be used to output and input ...
