Arduino for Beginners - 2022 Complete Course - Activity 12 - Solution

This video tutorial explains how to use interrupts to print an increasing counter on a serial monitor whenever a button is pressed. It covers setting up the button pin, defining an interrupt function, implementing flag and debounce logic, and using a loop function to handle the button press and increment a counter. The tutorial concludes with testing the code and observing the counter increment on the serial monitor.

What is the purpose of the interrupt function in the code?

How does the program ensure that the button press is registered only once per press?

Explain how the debounce mechanism is implemented in the code.

What is the significance of setting the 'last time' variable as volatile?

Describe the role of the global variable 'counter' in the program.

In what way does the program utilize the Serial Monitor for output?

What happens when the button is pressed and released multiple times quickly?
