simple program

Using Arduino Programming Questions
#1

Hey guys,

I havent programmed in a long time, and I am trying to remember a few programming skills, but it seems a little harder than what I thought. I need a program that when an input "2 or 3" is rising, or goes high, the LED on the board flashes 3 times or something like that.
Ideally, I am going to be testing to make sure that the input pins are working.

This is what I have, but I am stuck at the moment, I dont know if an "if" statement will make it work

const int led = 13;
const int WheelSpeedPin2 = 2;
const int WheelSpeedPin3 = 3;

void setup() {
pinMode(led, OUTPUT);
pinMode(WheelSpeedPin2, INPUT);
pinMode(WheelSpeedPin3, INPUT);

attachInterrupt(0, change_int_pin2, RISING);
attachInterrupt(1, change_int_pin3, RISING);

Serial.begin(9600);
}

void loop() {

}

void change_int_pin2()
{
digitalWrite(led, HIGH);
delay(5000);
digitalWrite(led, LOW);
}

void change_int_pin3()
{
digitalWrite(led, HIGH);
delay(5000);
digitalWrite(led, LOW);
}

Any help will be greatly appreciated.

Don't use delays in an interrupt service routine.
You may find your task simpler if you don't use interrupts at all.
Have a look at the blink without delay tutorial.

AWOL,
I appreciate the prompt response.
I can try to use the “blinkwithout delay” function.
But the rest of the code that I have, does it look like it works properly?

Like I said,
all I want the board to do is to blink or do something,
indicating that pin 2 or 3 has gone high, rising or whatever.

Thank you

Do your "delay"s work correctly?
If so, go with it.
If not, time for a rethink.
