When I run the below code with "buzzer_make_sound" in "loop()" the buzzer works as expected. Timer interrupts are triggered by one of the Arduinoâs internal timers. byte Second 30 // Interrupt Pin used static const byte wakeUpPin 2.include ![]() I am writing a really simple program in the Arduino environment using an Arduino Nano. ISR has following syntax in Arduino: attachInterrupt (digitalPinToInterrupt (pin). ![]()
