A very simple example that blinks LED1. LED1 blinks around 2 times a second. LED1 is located in the bottom left hand corner of the board.

The LEDs for the MBED-SDK and the Bambino line of microcontrollers are mapped to the following LEDs:

LED Colors
LED PIN NAME BAM210E BAM210 BAM200E BAM200
LED1 P6_11 Yellow LED Yellow LED Yellow LED Yellow LED
LED2 P2_5 Green LED Green LED Green LED Green LED
LED3 P6_1 RED LED RED LED n/p n/p
LED4 P6_2 Blue LED Blue LED n/p n/p 
/* Program Example 2.1: Simple LED flashing
                                                      */
#include "mbed.h"
DigitalOut myled(LED1);

int main()
{
    while(1) {
        myled = 1;
        wait(0.2);
        myled = 0;
        wait(0.2);
    }
}
