This project demonstrates an Arduino-powered wireless frequency meter that can measure the frequency of sinusoidal AC transmissions ranging from 50Hz to 3kHz. Figures 1 and 2 show prototype ...

This project is an Arduino-based distance detector that uses a servo motor, ultrasonic sensor, and LEDs to measure and display distances. It also includes multiple modes of operation controlled by ...

[robomaniac] shows us some serious application of modern technology with his recent Instructable, (the) Arduino-Fart-O-Meter. The wireless device uses a “perfboard Arduino” to read a remote wired ...

[Andrew] got a little help from his friends to hack a laser distance meter. Using laser distance meters as sensors is one of the great quests of hackers – with good reason. Accurate distance readings ...
