This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot ...

Here is the diagram of my Arduino infrared close proximity sensor ... light and by detecting its reflection on a potential object in front of the sensor. Using pulsed light enables the sensor to ...

Most ambient lights and sensors are designed to generate light to even out the picture ... He even provides the wiring diagram for his controller and the config file for his lights.

That makes it ideal for applications like robotics or controlling smart blinds that react to light ... convenient. Arduino is ...

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 ...

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.
