Arduino for Beginners - 2022 Complete Course - Add the Photoresistor to Your Circuit

The video tutorial demonstrates how to set up a circuit using a photoresistor on Tinkercad. It begins by duplicating a previous circuit and adding a photoresistor. The tutorial explains the connection of the photoresistor to the ground and 5V, similar to a push button setup. It highlights the use of an analog pin to read data based on room luminosity. The video also shows how to interact with the sensor in Tinkercad and provides insights into the real hardware setup, emphasizing wire optimization.
