In this Arduino light sensor tutorial, I will go through the basics of setting up a photoresistor, so can detect changes in light easily.
Conclusion: In this application note we have seen LDR sensor interfacing with Arduino Uno board. Arduino board is also used for interfacing different types of sensors for applications. The typical sensors interfaced with arduino are sound sensor, gyro sensor, heartbeat sensor, gas sensor, GPS sens...
