A Boolean Algrebra Expression using Consensus Theorem

A cybersecurity research group in Israel has recently published a paper in which they describe the MOSQUITO attack—an attack that can reverse speakers and microphones in air-gapped computers, and use them to send data to one another using ultra-sonic frequencies.

This project will show you how to connect an ultrasonic sensor and an Arduino to turn on a light when motion is sensed.

How do designers cope with a system that has highly variable input amplitude yet requires fairly constant output amplitude? Let’s take a look.
