Arduino for Beginners - 2022 Complete Course - Step 11 - Print Luminosity and Adjust the Lighting from the Photoresistor

The video tutorial guides viewers through the final project of a course, focusing on using a photoresistor to measure light and control a green LED and an LCD screen. The tutorial covers setting up the photoresistor and LED, implementing loop functionality for continuous checking, creating functions for LED and LCD operations, and implementing mode switching for the LCD display. The project is compiled and tested to ensure all components work together seamlessly.

How does the project differentiate between the photoresistor and ultrasonic sensor?

What is the role of the analog write function in controlling the LED brightness?

How does the project ensure that the luminosity is printed on the LCD only when appropriate?

What are the implications of using a switch for mode toggling in the project?
