Darkness Meter

This is a Darkness Meter. No, not the kind that that gauges the morality of an individual (LOST). But the kind that measures the amount of light in the ambiance. It works the same way as the "LDR and Arduino" project, but it has 3 LED's and 3 thresholds. I'm uploading a video of it in the next hour.

Arduino Button LED

The above picture depicts a button. The button is an addition to the LED program. When the button is pushed, the LED turns on and when it is released the LED turns off. The code can also be tweaked to make the button act like a light switch.

Arduino First Program LED

This is the Arduino Duemilanove. It is a micro controller. The image above is showing the Arduino lighting up a green LED. 

An Arduino can literally do anything if it is given the tools it needs. With enough know-how you can make it fly by giving it wings or you can make it talk by giving it a voice .
