New research shows that ultrasonic vocalizations emitted by mice in pain trigger hyperalgesia in nearby mice, even without ...

How it works is simple: you can track devices using Bluetooth on the ESP32, and through a combination of presence and signal strength, you can define a sensor that changes to an "on" state when your ...

Build your own interactive laser chasing toy for your dog using Arduino! In this DIY project, we use simple components like a laser module, servos, and motion logic to create a fun, automated game ...

Grace Musoki, another student participant, called on the government to ensure access to equipment and funding to help ...

This paper introduces a pioneering approach to ultrasonic-based distance measurement using ultrasonic sensors. Recognizing the influence of diverse weather cond ...

In this letter, we proposed an ultrasonic sensor-based resolution tunable displacement measurement system by using an extension spring. In the proposed method, a linear extension spring is vertically ...

This Arduino code utilizes an ultrasonic sensor to measure distances. When an object is detected within a fix distance , the connected motors trigger a sequence: move backward, turn right, turn left, ...
