This video tutorial demonstrates how to use the IF statement to control an LED with a button. It begins with setting up a simple circuit involving an LED, a button, and resistors. The tutorial then moves to programming the circuit using an IDE, where variables are declared, and pin modes are set. The main focus is on implementing IF statements to turn the LED on or off based on the button's state. Debugging tips are provided, highlighting the importance of using the correct operators. The tutorial concludes with optimizing the code using ELSE statements for default behavior.
