This stops the program that the processor was previously executing. Interrupts can be caused by various events - such as external events and timers . They help to perform tasks that are not part of the main program and can be done simultaneously as the rest of the program is running. This is known as asynchronous execution. In practice, interrupts are generally used to: Execute a Python function with a specific code that can be automatically triggered when a button is pressed. Run functions at a specified interval, such as flashing an LED every 5 seconds. It is possible to write code to turn on an LED when a key is pressed without using interrupts. However, this technique has two significant disadvantages. The first problem is that the script must constantly check the value of the pin_button pin to determine if the button has been pressed.
