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 proof-of-concept is just waiting for you to put it to good use. [Mike Tsao] wrote an Arduino sketch that lets him decode incoming audio data which could be used to program the device. He&#8217… ...

The source code for the project is based on the AeroQuad [open source quadcopter]. And yes, the 3D-printed, Arduino-powered quadcopter did take flight. Here it is: Quadcopter test flight.

Over the summer [ElectroSmash] put the finishing touches on the Arduino Audio Meter, a shield for the Arduino Uno that visualizes various aspects of an incoming audio signal on a set of four 8×8 ...

An Arduino is a microcontroller — a single board designed to control something and perform a specific task. Unlike a Raspberry Pi, you won't find anything resembling an operating system here ...

Through this hands-on, project-based approach to learning, you'll grasp a solid understanding of Arduino components like ultrasonic sensors, motor drivers, servos, and transistors.

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.

IC3 is a TDA2822D Audio Amplifier by STMicroelectronics, whose output is sent to both the 6.3 mm L and R female mono output jacks and to the headphone 3.5 mm stereo output jack on the rear side of the ...

The Oplà IoT Kit follows the recent launch of the Arduino Explore IoT Kit (€99.00), featuring 10 step-by-step online education activities. That kit was aimed at high school and college students ...
