This design, based on a Maxim MAX220 RS-232 driver/receiver IC, allows you to increase the number of USARTs (universal synchronous, asynchronous receiver/transmitters) available on a microcontroller.

The myriad processes occurring in biological cells may seem unbelievably complex at first glance. And yet, in principle, they are merely a logical succession of events, and could even be used to form ...

This video explains how transistors work as switches and amplifiers in electronic circuits. Transistors control the flow of current and enable signal processing in everything from small devices to ...

The demonstration of a microcavity polariton switch and logic gate that can be controlled by the polarization state of light suggests that a new class of integrated optical devices with highly ...

Engineers have created genetic circuits in bacterial cells that not only perform logic functions, but also remember the results, which are encoded in the cell's DNA and passed on for dozens of ...
