LED Circuit and Tinkercad Concepts

In this lesson, Professor Douglas continues the Arduino course by guiding students through building and programming a traffic light circuit using the Tinkercad platform. The lesson covers setting up the circuit with LEDs and resistors, programming the traffic light sequence using block-based coding, and running simulations to ensure functionality. The session concludes with a preview of adding a button for pedestrian control in the next lesson.
