This example code is in the public domain.
// difference between the current time and last time you blinked
// the LED is bigger than the interval at which you want to
// blink the LED.
- unsigned long currentMillis = millis();
- if(currentMillis - previousMillis > interval) {
+ if(millis() - previousMillis > interval) {
// save the last time you blinked the LED
- previousMillis = currentMillis;
+ previousMillis = millis();
// if the LED is off turn it on and vice-versa:
if (ledState == LOW)
/* Domande
1. Aggioungere un LED che brilli ogni 500ms
- 2. E' possibile cambiare gli intervalli dei due LED?
+ 2. E' ora agevole cambiare gli intervalli dei due LED?
