An era once existed when a six-inch screen would’ve been huge for a phone. Reader, I was there. That time has passed and nowadays it’s apparently considered a compact smartphone. Smaller flagship ...

Abstract: This paper provides details about the design and operation of a Collision Avoidance System in smart cars, with the Arduino board as the central control unit, interfaced with an ultrasonic ...

The ultrasonic beam from this sensor penetrates the skin, detects signals reflected from the vessel walls, and measures changes in vessel diameter. Using this principle, it measures the real-time ...

Ultrasonic sensors measure the distance between a target and the sensor using high-frequency sound waves that are inaudible to humans. The process is simple: the sensor emits ultrasonic waves, which ...

Designed to accelerate advances in medicine and other fields, the tech giant’s quantum algorithm runs 13,000 times as fast as software written for a traditional supercomputer. A quantum computer at ...

I built a mini radar system using Arduino UNO, HC-SR04 Ultrasonic Sensor, and SG90 Servo Motor, paired with a JavaScript-based visualization dashboard 🖥️. The servo sweeps from 0° to 180°, collecting ...

As robots increasingly enter human spaces, robotics companies will need to think about safety differently than they did when robots were largely siloed from their human counterparts. Sonair thinks its ...
