HINT_for_my_Solution

I think many signals make error.
So, I use add only

delay(1)

to stop interrupt. (in void loop())

Timer

delay(time in milliseconds)

millis()

Timer Interrupt

const long interval = 1000; 
unsigned long currentMillis = millis();
if (currentMillis - previousMillis >= interval) {
    previousMillis = currentMillis;
}
