const int COL1 = 3; // Column #1 control
const int LED = 26; // 'row 1' led

const int BUTTON_A = 5; // The number of the pushbutton pin
const int BUTTON_B = 11; // The number of the pushbutton pin

long previousMillis = 0;
long currentMillis = 0;
int interval = 500;
boolean ledState = false;
boolean buttonAPressed = false;
boolean buttonBPressed = false;

void setup()

  Serial.println("microbit is ready!");

  pinMode(BUTTON_A, INPUT);
  pinMode(BUTTON_B, INPUT);

  // Because the LEDs are multiplexed,
  // we must ground the opposite side of the LED
  pinMode(COL1, OUTPUT);
  digitalWrite(COL1, LOW);

  pinMode(LED, OUTPUT);

void loop()
  currentMillis = millis();
  if (currentMillis - previousMillis > interval) {
