Read button state arduino
WebMonitor the button’s state void loop() { byte buttonState = digitalRead(BUTTON_PIN); The first thing we do is to read the button’s state and to store it inside a new local variable. if (buttonState != lastButtonState) { Then we can compare the current state to the last one (from the previous execution of the loop function). 4 possibilities here:

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. WebMay 6, 2024 · The code to check whether the button was pressed should be referred to as a block, not a loop. And, yes that block of code goes into the loop function.
