int D5 = 5;
int D6 = 4;
int D7 = 3;
int D8 = 2;
// the setup routine runs once when you press reset:
void setup() {
// initialize the digital pin as an output.

delay(200); // wait for a 200 Millisecond
digitalWrite(D1, LOW); // turn the LED off by making the voltage LOW
digitalWrite(D2, HIGH); // turn the LED on (HIGH is the voltage level)
delay(200); // wait for a Millisecond
