I'm just learning how to use the Arduino Uno and I'm trying to control the speed of an AC fan. I made a sketch of this project on proteus but the triac seems not to be responding. I guess there's a problem with the attachInterrupt part of the code. Here's the code:

#define triacPulse 5 #define interruptPin 2

//button event #define button1 6

void setup() { // put your setup code here, to run once: pinMode(button1, INPUT);

}

void loop() { // put your main code here, to run repeatedly: if(button1==HIGH){ attachInterrupt(0, triacControl, FALLING); } }

void triacControl() { delay(5); //delay for 5 milliseconds digitalWrite(triacPulse, HIGH); delay(5);

digitalWrite(triacPulse, LOW);

}

Thanks for the answer in advance
