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.
