digitalRead in Ardiuno: Arduino Course 4.10

This video tutorial covers the use of Arduino pins as inputs, focusing on setting up a simple button circuit. It explains how to use the digital read function to detect button presses and display the results on a serial monitor. The tutorial includes a practical scenario where a button press signals coworkers about an approaching boss. The video also provides a detailed explanation of the circuit setup and the corresponding Arduino sketch, emphasizing the importance of avoiding floating pin values.
