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 ...

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

The creator of the Arduino RF Pro Mini open source development board ... I made the observation that, if you want to build a sensor that runs on batteries, you have to buy the arduino and the ...

Aerial drone footage shows the humpback whale (Megaptera novaeangliae) missing its iconic lobed fluke, which is responsible ...

Finally, the Arduino MKR Motor Carrier can be used with the MKR boards for prototyping. It can be used to connect up to four motors and sensors to control servo, DC and stepper motors as well as ...

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 ...

Have you ever wished you could see in the RF part of the radio spectrum ... [Ken] even came up with an Arduino with a gas sensor that talks to the phone and maps the atmosphere around the kitchen ...

The Pressure Sensor Module incorporates a material called Velostat with the Arduino. This material adds more resistance when more pressure is applied to the material. This module also uses the RGB LED ...
