Search around online IoT communities and resource sites such as thingspeak and you can find several examples of Wi-Fi-based, Arduino-sourced projects that include a popular wireless sensor application ...

The Saturn’s electronics aren’t sophisticated enough to implement a lean burn system simply, and so [Robot Cantina] did what any of us might have done: hacked it in with an Arduino.

Learn how to create a simple heart rate monitor using an Arduino Pro Mini, PulseSensor, and OLED display. This ...

That’s right, these parking sensors are powered by an Arduino board, and the only extra components that were used in the project are a HC SR04 ultrasonic sensor, an active buzzer, and jumper wires.

Come and get started with Arduino, a user-friendly microcontroller platform that will allow you to build anything from a weather station to a wearable electronic device. This session will provide an ...

Voltmeters aren’t terribly expensive, but it’s always more fun to build your own devices. YouTube DIYer Educ8s builds a cheap voltmeter for less than $10 using an Arduino and a voltage sensor.

The build settles on an Arduino Pro Micro, as it uses the ATmega32U4 which eliminates secondary USB-to-serial chips, helping cut down on power consumption.
