Arduino Interupt Pinleri

Arduino Interruptlar volatile byte half_revolutions; unsigned int rpm; unsigned long timeold; void setup() { Serial. begin(115200); attach. Interrupt(0, magnet_detect, RISING); //Initialize the intterrupt pin (Arduino digital pin 2) half_revolutions = 0; rpm = 0; timeold = 0; } void loop()//Measure RPM { if (half_revolutions >= 20) { rpm = 30*1000/(millis() timeold)*half_revolutions; timeold = millis(); half_revolutions = 0; //Serial. println(rpm, DEC); } } void magnet_detect()//This function is called whenever a magnet/interrupt is detected by the arduino { half_revolutions++; Serial. println("detect"); }

// toggles LED when interrupt pin changes state int pin = 13; volatile int state = LOW; void setup() { pin. Mode(pin, OUTPUT); attach. Interrupt(0, blink, CHANGE); } void loop() { digital. Write(pin, state); } void blink() { state = !state; }
