Blink onboard LED

Next it's time to load up a program on your FLORA. There is an LED on board, so let's blink it! Plug in the USB cable and paste the following code into the Adafruit Flora IDE:
// Pin D7 has an LED connected on FLORA.
// give it a name:
int led = 7;

// the setup routine runs once when you press reset:
void setup() {                
  // initialize the digital pin as an output.
  pinMode(led, OUTPUT);     

// the loop routine runs over and over again forever:
void loop() {
  digitalWrite(led, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);               // wait for a second
  digitalWrite(led, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);               // wait for a second
From the Tools menu, under "Board," choose "Adafruit Flora"
Also in the Tools menu, under "Serial Port," choose the one that contains the phrase "usbmodem" if you have a Mac.
If you're using a Windows computer, it will be named COMsomething, but not COM1 or COM2 (so it will be whatever comes after those two if they exist, such as COM3 or COM4).
Press the Upload button to transmit the program to the FLORA. It looks like an arrow pointing to the right.
That's it! The on board LED marked "D7" should blink on and off repeatedly, and you've successfully programmed your FLORA!
