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 ...

In this blog ... the LDR sensors and calculates the position of the sun in the sky. The Arduino Uno then controls the servo motors to rotate the solar panel on both the X and Y axis to track the ...
