Light sensors are widely used in electronic applications. The most common one used is a photoresistor or light-dependent resistor. Despite a long response time, this sensor is inexpensive and useful ...

Hi Everyone, This is my 1st Arduino's tutorial video. In this video i am going to show you how to use a LDR or Light Dependent resistor to turn on and off another circuit or a LED. Wouldn’t it be ...

When constructing the sensor, consider these things. The LDR should only be exposed to the reflected light from the surface which was emitted by the RGB LED. Light from the RGB LED should not directly ...
