Arduino: Light Indicator with multi-LED bar graph and light sensor.

October 25, 2012 Leave a comment Go to comments

This project refers to an Arduino sketch that implements a light indicator with the help of an external sensor (photoresistor) for the recognition of light, and a bar graph of many LEDs used as a rating indicator. Furthermore, if the indicator reaches the last rating which indicates that there is “perfect” light (the maximum light that the sensor can identify) then it plays a melody with a piezo speaker located in the system.

For more information you can get the project itself:
