Thank you for this useful and well-made video. I've successfully programmed an ATtiny45 with that example now and it works very well.

Great video! Good explanation. very easy to understand. Thank you.

Why do you use a whole library when you can simply do:
void setup() {
GIMSK =
PCMSK =
sei();
}
ISR(PCINT0_vect) {

}

So, for Rising Edge of INT0 to generate an Interrupt Request...? Would it be...
MCUCR |=(1<<ISC00);
MCUCR &=(1<<ISC01);
and shouldn't that be in the setup void?


Is all of your code there compatible with the Arduino IDE? or Atmel Studio only?

Hi, thanks for the video - it looks great. However, it does not work for me. Can you show the pin outs on a breadboard, please. From pin 5 I have an LED then resistor -> GND. I have a connection from pin 7 to the button and from the other button connector is connected to GND.

What is the Title i search for when looking up that "avr/interrupt.h" library?
