In this lecture, you will learn how to convert the raw value from the photoresistor to something useful, such as Lux. Lux is commonly used as a unit for measuring illuminance.
This project course is ideal for the new Arduino maker looking for a weekend IoT challenge. It gives you the opportunity to complete your first Arduino project that is non-trivial, combines modern hardware and software components, and includes an Internet of Things element.

This tutorial introduces how to integrate a push button into your Arduino projects to control an LED. Using a digital input pin, youll learn to read the state of the button and use its status to turn an LED on and off. This project builds on our previous tutorial by adding a push button and demonstrating how to set up and code for interactive elements. Through the demonstration, youll understand how to handle button states and debouncing, enhancing the interactive capabilities of your Arduino projects.
