This Arduino-powered Shiftbrite LED ambilight setup takes things a step further by automatically adjusting the color and intensity of the ambient lights on the back of the display to match ...

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 ...

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 ...

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 ...

treating the recharging circuit from the emergency lights as the most likely culprit. Since the ECG is many times more sensitive to EMF than the Arduino, this turns out to be a quick and easy way ...

Instructables user CarlS powered through a big Arduino project with digital LEDs. He created a holiday lights system that can last through the entire holiday season without having to manually ...
