A simple way to test this is to use an ‘if’ statement to check the value stored in ‘btstate’ and then turn on an LED if it is ‘HIGH’ or turn it off if it is ‘LOW’. Note that the LED will only stay on while the button is depressed, and will shut off when you ...

Serial.println(digitalRead(BUTTON_PIN)); delay(10); } If you run this code and open the Serial Plotter, you’ll see that the default value is 1 (HIGH). When you press the button the state directly goes to 0 (LOW) and comes back to HIGH when you release the button. ...
