This project uses an ultrasonic sensor and an Arduino to measure distance and dynamically control the brightness of an LED. As an object moves closer to the sensor, the LED becomes brighter. As the ...

Driving at night often causes discomfort and accidents due to improper usage of high-beam headlights. This project aims to automatically dim headlights when oncoming vehicles are detected, improving ...

The nano sensor interface presented below is a microcontroller-based universal sensor interface with a power-saver mechanism. The idea, centered around an Arduino Nano (v3) microcontroller, was ...

This one is an unusual smart home project, potentially - how to monitor a fish tank’s health with an AI-enabled ultrasonic sensor system. The detailed project is highlighted on Hackser.io and features ...

[Mike] lives in a temperate rainforest in Alaska (we figured from his website’s name) and uses a 570 gallon oil tank to supply his furnace. Until now, he had no way of knowing how much oil was left in ...

[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors. The ...
