Focus on One Area: Robotics is broad. You could focus on programming first, then move to electronics, or vice versa. Trying ...

Microcontrollers for Kids shows a classroom-tested path from Scratch to Open Roberta to Arduino UNO, with printable coding ...

Abstract: Horizontal gas-liquid slug flows are widely encountered in important industrial processes. Bubble velocity measurement is of great significance for understanding the heat/mass transfer and ...

Abstract: Non-destructive inspection of concrete structures is often made using an ultrasonic sensor. With the conventional methods, however, a high reliable detection of anomalous parts (as cracks ...

Female moths don’t rely on sight or smell alone. They can also hear stressed plants. Scientists found that these insects detect ultrasonic clicks from plants under drought stress and use them when ...

This project utilizes an Arduino Uno CH340G development board paired with a DHT11 temperature and humidity sensor to create a compact yet capable environmental monitoring system. It measures ambient ...

A new technology has been developed that enables cuffless noninvasive blood pressure monitoring by using ultrasonic to track real-time changes in vascular diameter—without the need for a traditional ...
