LDR Sensor Output on Serial Monitor Using Arduino | Beginner Project
In this video, I show how to read light values using an LDR sensor with Arduino and display the output on the Serial Monitor.
An LDR (Light Dependent Resistor) is a light sensor whose resistance changes when light falls on it. Arduino reads this changing value using an analog pin and shows the readings as numbers on the Serial Monitor.
By covering and uncovering the LDR, we can observe how light intensity changes the sensor values.
This project helps beginners understand:
• What an LDR sensor is
• How Arduino reads analog values
• How sensors provide data for real-world applications
In my upcoming videos, I will use these values to control LEDs and build automatic light projects.
*Components Used:*
• Arduino board
• LDR (Light Dependent Resistor)
• Resistor
• Breadboard
• Jumper wires
