The Complete Beginners Guide to Arduino - 2021 - Interactive Traffic Lights

This tutorial explains how to make a traffic light simulation interactive by adding a button. It covers wiring the button to an Arduino Nano, modifying the code to include a button press detection, and using a while loop to control the traffic light sequence. The tutorial ensures that the traffic light system allows vehicles to move and pedestrians to cross safely, with a delay to prevent constant button pressing.

How does the code handle the state of the button during the main loop?

What is the initial state of the traffic lights before the button is pressed?

What happens if the button is pressed repeatedly before the 10-second delay is over?

Summarize how the traffic light sequence is changed to be interactive.
