How to Program a Push Button with Arduino

As I have been getting less and less time to create videos and write articles I won’t be writing an article about this video. I will simply provide the video instruction and the code, I hope this is still helpful.

// setup pins
const char BUTTON_PIN = 8;
bool pressed = false;

void setup() {
  Serial.begin(115200);

  // Setup pin modes
  pinMode(BUTTON_PIN, INPUT_PULLUP);
}

void loop() {
  // Read button
  bool currentState = digitalRead(BUTTON_PIN);

  if (currentState == pressed) {
    Serial.println("Hello");
    while(digitalRead(BUTTON_PIN) == pressed) {
      // Do nothing while button is pressed
    }
  }
