WebMar 2, 2024 · The second type, called hardware-interrupts, allows you to react to external events that change the state of one of the Arduino’s General-Purpose Input/Output (GPIO) pins. Such events could be button presses, an external sensor signaling that it’s ready to read values, or the start of a data transmission sequence. WebJan 20, 2024 · void loop () { digitalWrite (MY_LED,HIGH); delay (1000); digitalWrite (MY_LED,LOW); delay (1000); //This code only gets reached every 2 seconds //This means you may need to hold the button for up to //2 seconds before it will print a message if (digitalRead (MY_BUTTON) == LOW) { Serial.println ("You pressed the button"); } }
WebA finite state machine (FSM) is a theoretical machine that only has one action or state at a time. The machine may go from one state to another if there are inputs (or one input) that triggers the state change..
