Hi Mr., I want to ask if using interrupt to replace pulsein, does it only read high? How do you read push button low, Mr.? Please, use interrupt to replace pulsein

My results do not match yours - will you please tell me why
#define buttonPin 2

void setup ()
{
Serial.begin (9600);
pinMode(buttonPin, INPUT);
}
void loop()
{
unsigned long duration = pulseIn(buttonPin, HIGH,
Serial.println (duration);
}

i pressed the button several times : 2sec, 2 sec, 2sec, 6 sec
these results were shown on serial monitor

Thanks for video! I try to do PWM switch (ON/OFF) with pulseIn() function like in your video. But there is no reaction. Could you help me to fix this problem?

Good video thanks for making this, very helpful!

Good explanations thank you for teaching 💕

hi would this work if i was to count the pulses that come off a 24 v coin mechanism? My coin mech sends a pulse each time a quarter is deposited?
