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 ...

If you do not know about LED and ultrasonic sensor (pinout, how it works, how to program ..), learn about them in the following tutorials: -Arduino-LED tutorial ...

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 ...

Here is a simple Arduino Camping Light project. In this design ... This part number (and ofcourse the LED type) is not very critical. If you want to use a bi-polar transistor, don’t forget to add a ...

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 ...

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 ...

This project demonstrates a simple water detection system using an Arduino board and a water sensor. The system uses an LED to indicate whether water is detected. The LED turns ON when no water is ...
