Arduino for Beginners - 2022 Complete Course - Read the Luminosity from the Photoresistor

The video tutorial explains how to use a photoresistor with an Arduino to measure light intensity. It covers setting up the circuit, reading sensor values, and interpreting the data. The tutorial also discusses testing the sensor in different lighting conditions and defining thresholds for various light levels. Additionally, it demonstrates using the Arduino IDE's serial plotter to visualize data changes.

What is the purpose of the photoresistor in the circuit?

Explain how to read values from the photoresistor using the analog array function.

How can you interpret the values obtained from the photoresistor?

What values can you expect to read from the photoresistor in different lighting conditions?

Describe how you would use the serial plotter in the Arduino IDE with the photoresistor.
