This sketch reads a piezo element to detect a knocking sound. It reads an analog pin and compares the result to a set threshold. If the result is greater than the threshold, it writes "knock" to the ...

Abstract: This paper introduces an Arduino-based color-sorting conveyor belt system that automates object sorting by color. Employing a TCS3200 color sensor, an Arduino microcontroller detects red, ...

You might think traffic light systems are fairly basic. After all, electric traffic signals first appeared all the way back in 1914. However, they have advanced significantly since their inception, ...

Smartphone cameras are becoming smaller, yet photos are becoming sharper. Korean researchers have elevated the limits of next-generation smartphone cameras by developing a new image sensor technology ...

Researchers have developed a highly sensitive light-based sensor that can detect extremely low concentrations of cancer biomarkers in the blood. The new technology could one day make it possible to ...

Designed by Nova Radio Labs in the US, the Novaduino Environmental Sensor Kit is an Arduino-programmable air quality and weather monitoring solution built around the company’s own Novaduino Display ...

Presence/motion sensors are one of the best ways to make automations feel more natural, but most of them run on batteries and eventually have to be swapped. That’s one of the main reasons I really ...
