How can I check the status of a button using the digitalRead() function in Arduino?
To check the status of a button using the digitalRead() function in Arduino, you need to connect the button to a digital pin on the Arduino board. Then, in your Arduino code, you can use the digitalRead() function to read the state of the pin where the button is connected. If the button is pressed, the digitalRead() function will return HIGH, and if it is not pressed, it will return LOW. You can then use this information to perform different actions in your code based on the status of the button.
