Hello, I am quite new to Arduino and this is only my 4th or so program so this may be why I'm confused.
I wrote a small example to showcase my problem:
void blink()
{
digitalWrite(pin, HIGH);
delay(100);
digitalWrite(pin, LOW);
}
void setup() {
pinMode(pin, OUTPUT);
}
void loop() {
// put your main code here, to run repeatedly:
blink();
digitalWrite(pin, HIGH);
delay(100);
digitalWrite(pin, LOW);
delay(1000);
}
Even though I think it should blink twice with every loop, it only blinks once. This must be because the function isn't actually sending a signal (when I remove the function it still blinks).
Why is this? Is there a way to make the LED blink through a function? Thanks in advance.
