On State

Switches the component on.

void function_0_led(){
digitalWrite(pin_0_led, HIGH);
function_0_led();
}

digitalWrite(pin_0_led, HIGH);

void function_0_led(){
digitalWrite(pin_0_led, HIGH);
state = 1;
}

Off State

Switches the component off.

void function_0_led(){
digitalWrite(pin_0_led, LOW);
function_0_led();
}

digitalWrite(pin_0_led, LOW);

void function_0_led(){
digitalWrite(pin_0_led, LOW);
state = 1;
}
