// Variables will change:

int buttonState = 0; // Variable to read the push button state

// The setup routine is run once when reset is pressed:

void setup() {

// Initialize the key pin as input.

digitalWrite(D5, HIGH); // Turn on the LED (voltage level is high)

digitalWrite(D6, HIGH); // Turn on the LED (voltage level is high)
