Sometimes, the best Arduino projects are the most ridiculous. Case in point, this motion-detecting squirt gun.The idea is simple: when it detects motion, the spray gun activates.

An Arduino can be used to test the life of any battery with less than 5 volts, Boxall says. So, for a quick way to see how much juice your AAA, AA, C, or D batteries have left, build this Arduino ...

This project uses an Arduino Uno CH340G clone and a DHT11 sensor to build a compact weather station that measures temperature and humidity, calculates over ten derived environmental metrics, and ...

5 projects best suited to an Arduino, not a Raspberry Pi. Story by Patrick Hearn • 3mo. A n Arduino is a microcontroller — a single board designed to control something and perform a specific task.

The magic lies in Arduino's Modulino nodes, which consist of various sensors and actuators that connect to the UNO R4 WiFi board. The Plug and Make Kit is a complete package to get started. Inside ...

Lasers are some of the coolest devices around. We can use them to cut things, create laser light shows, and also as a rangefinder.[Ignas] wrote in to tell us about [Berryjam’s] AMAZING write-… ...

As much as we love the Arduino Uno, it's not the most powerful of hobbyist microcontrollers. Fortunately, the folks in Turin have just put the finishing touches on a 32-bit upgrade with buckets of ...

The Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller and developed by Arduino.cc. It was first developed back in 2003 as an affordable ...
