![]() ![]() Int buttonState = digitalRead(BUTTON_PIN) the pull-up input pin will be HIGH when the switch is open and LOW when the switch is closed. initialize the pushbutton pin as an pull-up input initialize serial communication at 9600 bits per second: const int BUTTON_PIN = 7 // the number of the pushbutton pin Now copy the following code and upload it to Arduino IDE Software. Here is a simple step-by-step guide on “ How to install Arduino IDE“. Wiring / Connections Arduinoįirst, you need to install Arduino IDE Software from its official website Arduino. Make connections according to the circuit diagram given below. Finally, the code is uploaded to the Arduino board and the pushbutton is pressed and released to check the status on the serial monitor.This can be viewed by opening the Serial Monitor in the Arduino IDE and setting the baud rate to 9600. The Serial.println() function is used to print the string to the serial monitor.If the value is LOW, it means that the button is not pressed and we print “Button released” to the serial monitor. If it is equal to HIGH, it means that the button is pressed and we print “Button pressed” to the serial monitor. We then use a if-else statement to check the value of the buttonState variable.In the loop() function, we read the state of the pushbutton using the digitalRead() function and assign it to the buttonState variable.We also initialize serial communication using In the setup() function, we initialize the pushbutton pin as an INPUT using the pinMode() function.Next, we create an integer variable named buttonState to store the current state of the pushbutton.In this case, the pushbutton is connected to digital pin 2, so we create a constant integer variable named buttonPin and assign it the value of 2. The first step is to define the pin number to which the pushbutton is connected.
