A previous Design Idea described a single-wire-plus-ground-return, keypad-to-microcontroller interface in which a single pulse represents each keystroke (Reference 1). The pulse's width is ...

Creator, AstroSam, built a functional prototype of a brain-computer interface (BCI), called Mind Link. It reads brain signals from a simulated 32-electrode array and sends them to a computer to ...

Many microcontroller designs typically mix multiple interfacing methods. A microcontroller (µC) system can be viewed as a system that reads from inputs, performs processing and writes to outputs.
