Arduino for Beginners - 2022 Complete Course - Create a Circuit with 1LED and 1Resistor

This video tutorial introduces the basics of using an LED in a circuit, starting with a simple setup in Tinkercad. The instructor guides viewers through creating a circuit using an Arduino board and a breadboard, explaining the connections and components needed. The tutorial then transitions to building the same circuit with real hardware, emphasizing the importance of correct connections and component placement. Key concepts include understanding the roles of the anode and cathode in an LED, using resistors to limit current, and the significance of ground connections.
