Below, is an Arduino function for reading smoothly an average value from a jumpy or erratic analog input sensor. The function reads repeatedly from an analog input, calculating a running average and returns the value back to the caller.

This project refers to an Arduino sketch which has the capability to send measurements collected by a light sensor to an account at Twitter to be seen by many through the World Wide Web.
This project refers to an Arduino sketch which with the help of a relay (electromechanical switch) and a light sensor can drive an external device (e.g. a household lamp, a car alarm, a home air conditioner). More specifically, the Arduino collects samples from a light sensor at a specific rate and calculates the mean of samples for best accuracy. Then, if the average exceeds a threshold limit, it will activate the device via the relay. Also, the opposite happens where, if the average sensor value drops below the limit mentioned, the device is turned off.
