To supply targeting data for the launcher, an Arduino Uno uses an ultrasonic sensor pair mounted atop a servo. As the servo rotates, the returns from the ultrasonic sensor are plotted on a screen ...

While early scientists and inventors famously underestimated the value of radar, through the lens of history we can see how useful it became. Even though radar uses electromagnetic waves to detect ...

You simply connect your components to the board, use a software called Arduino IDE ... outfitted with a servo inside the bin for opening and closing the lid, an ultrasonic sensor in front of ...
