Four LEDs are built into the mbed board. This program flashes them on for 0.2 seconds and off for 0.2 seconds, repeating for ever.

#include "mbed.h"

// CONFIGURE FOUR OUTPUT LINES (FOR THE BUILT-IN LEDs)
DigitalOut myled1(LED1);
DigitalOut myled2(LED2);
DigitalOut myled3(LED3);
DigitalOut myled4(LED4);

int main() {
    while(1) {             // REPEAT FOR EVER
        myled1 = 1;        // LED ON
        myled2 = 0;        // LED OFF
        myled3 = 1;
        myled4 = 0;
        wait(0.2);         // 0.2 SECOND DELAY
        myled1 = 0;
        myled2 = 1;
        myled3 = 0;
        myled4 = 1;
        wait(0.2);         // 0.2 SECOND DELAY
    }
