Here I will discuss two examples – a new kind of piezoelectric motor, and ‘robo-buzzers’ for studying buzz-pollination: In the sub-gram regime, piezoelectric actuation can be preferable to ...

VFDs — vacuum fluorescent displays — have a distinctive look, and [Anthony Francis-Jones] is generally fascinated with retro displays. So, it makes sense that he’d build a VFD project as an ...

Using an Arduino Nano, ultrasonic sensor, and buzzer, it can sense objects in their way and provide an instant audible alert to them. So they can navigate independently. The best part of this blind ...

The Microcontrollers Hands-on Course for Arduino Starters is a comprehensive learning package aimed at people with little to no prior experience in electronics or programming. The course emphasizes ...

This is a customizable alarm system built using Arduino Mega, designed to detect motion using ultrasonic and IR sensors, and trigger a buzzer alarm when intrusions are detected. The system can be ...

A low-cost, reusable, and chemical-free fire extinguisher that uses sound waves to suppress small fires. Developed with an Arduino-based system, FireX offers real-time fire detection, SMS alerts, and ...
