USING AN LDR SENSOR WITH ARDUINO Introduction 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 ...

Working of LDR controlled LED using Arduino As per the circuit diagram, we have made a voltage divider circuit using LDR and 100k resistor. The voltage divider output is feed to the analog pin of the ...

As a real turbidity sensor (which is sold in electronics stores) usually has a high price, the idea of this project came to replace such equipment with lower-priced ones and obtain a similar result.
