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 Arduino. The analog Pin senses the voltage ...

Here three LDR sensors are used to control the brightness of ... Learn here to interface RGB LED with Arduino. The complete circuit diagram of this project is given above. The +5V and ground ...

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 ...
