The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

Arduino enthusiasts and beginners may be interested in a new add-on board designed for the Arduino Uno microcontroller featuring 10 of the most popular modules and sensors for the Arduino platform ...

This module provides an introduction to utilizing a gas sensor with the Arduino. It also demonstrates some warning systems that can be implemented with the sensor. Finally, it provides a sensor ...

Schematic of the ACS712 Current Sensor Circuit (tested circuit diagram of the current sensor module) The internal resistance of this conductive path is 1.2 mΩ typical, providing low power loss. The do ...

This morning, littleBits is introducing an Arduino module into the mix. It’ll snap right into place — no soldering required — just like the other littleBits modules, with one big difference ...

Because of the affordability and seeming ubiquity of the Arduino platform, they have been hard at work this last month trying to get their Geiger counter sensor board for an Arduino out the door.

In this fun project an ultrasonic distance sensor is used to detect a “target” (i.e., a person, a cat, a burglar, etc.). The Arduino illuminates (blasts) the target using an inexpensive laser diode ...

He suspected EMF interference so as a quick first step he decided to throw together an EMF detector using an Arduino. It uses a bank of LEDs as an indicator bar to reflect the EMF picked up by the ...
