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 ...

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 ...
