Arduino Issue: LED flickers off when using switchcase and serial monitor input via the keyboard

This video tutorial addresses a common issue with switch case statements in Arduino programs, particularly when triggered by input from the serial monitor. The tutorial walks through a code example, identifying the problem caused by ASCII control characters being added to the input. It explains how these characters affect the program's behavior and provides a solution by setting the serial monitor to 'no line ending'. The video also covers the role of control characters like newline and carriage return, and demonstrates the solution with practical examples.
