Faris,

Thanks for the question :)

Which LED on the board are you referring to?

For this board only LD2 is able to be user controlled.

You can see that LD1 is for the STLINK, and LD3 is solid RED for power.

Hope that helps.

Regards,

Andrea, team mbed

Are you asking for something like this? This is blinky code

#include "mbed.h"

DigitalOut myled(LED1);

int main() {
    while(1) {
        myled = 1; // LED is ON
        wait(0.2); // 200 ms
        myled = 0; // LED is OFF
        wait(1.0); // 1 sec
    }
}

Thank you bill ;)
