Optimizing Code Efficiency: Mastering Conditional Debugging with

Explore how to enable or disable "Serial.printf" statements for code debugging. We showcase the effectiveness of using #define, enabling these statements to stay in the code without compilation, ensuring zero impact on code execution time when debugging is unnecessary.
