Arduino Basics Hardware Interrupt Part 1
In this video we introduce the hardware interrupt. The hardware interrupt is something external that the MCU checks for on every clock cycle. Think of the ATMega328P like a 3 year-old in the back seat of your car asking "are we there yet?" Thats what the hardware interrupt does to your Arduino.

Loved your teaching style . Like you musical taste. Met they guys in casting crowns in about 2004, when I was house crew in a theater in Montgomery AL. Great people.

Till now I thought that the setup function run once only and the loop function infinitely.
Why it keep running the setup function after the first push bottom, it should go through the sketch to the loop function an stay there !
Does the loop function run at alll ?

That seems to indicate that the interrupt function would just start over and over if you have a noisy input. (Like a bouncy button or an IR proximity sensor) Does the interrupt function have to run completely before the interrupt will call it again?

The problem is these Arduino are complete garbage and unreliable for anything critical
