In this experiment we are going to use a element called photoresistor. This sensor allows us to interact with the external environment, through intensity of light. The photoresistor is based on light ...

This project uses an Arduino board with a photoresistor sensor and a GSM shield to send an SMS message when the light level detected by the sensor falls below a certain threshold. Connect the GSM ...

Light Switch Is an Arduino project in which we construct a circuit that can be activated by shining a light on the sensor. It incorporates a photoresistor sensor (KLS6-3537), an n3904 transistor ...
