Shea's first arduino code

One more step toward her eventual balloon flight has started: teaching her how to write control code for an arduino microcontroller. She took to it pretty well and quickly had a couple of LEDs blinking on and off. Tomorrow we talk about reading sensors.

/*
Blink
Turns LED on and off repeatedly
*/



void setup() {

pinMode(12, OUTPUT);
pinMode(4, OUTPUT);
pinMode(2, OUTPUT);
pinMode(8, OUTPUT);

}

void loop() {
digitalWrite(12, HIGH); //1 on
delay(500); //pause
digitalWrite(12, LOW); //1 off
digitalWrite(4, HIGH); //2 on
delay(500); //pause
digitalWrite(4, LOW); //2 off
digitalWrite(2, HIGH); //3 on
delay(500); //pause
digitalWrite(2, LOW); //3 off
digitalWrite(8, HIGH); //4 on
delay(500); //pause
digitalWrite(8, LOW); //4 off
