which measures the intensity of light bouncing back from an object as an Arduino drives the LED through all possible colors with PWM signals. The sensor needs to be white balanced before use but ...

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 ...

Most ambient lights and sensors are designed to generate ... light bleed from the back of an LCD display. This Arduino-powered Shiftbrite LED ambilight setup takes things a step further by ...

Using motion detectors and an Arduino you can trigger lights, fans ... Check to see if the sensor is triggered; if it is, flash the on-board LED in front of digital pin 13. This is a good way ...

If you are designing your own intelligent “Graden Computer” with an optional digital plant moisture sensor/water pump controller that lights an LED to alert the user when ... here is an Arduino Primer ...

Because his blinkenlight shield can be used as a light sensor, all that’s needed is a mirror and a pretty long line of sight. There’s a few problems with the setup though: with the Arduino ...

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 ...
