Timer

Is it possible to use the timer to count down from 10 sec and once it hit 0, it will lets say turn off a led or enable a pin?

Yes. Well the timer itself is an upcounter, but you can do the same by letting it count up to 10 secs and do something once it reaches that. For example:

Timer timer;
DigitalOut led(LED1);

timer.start();

while(timer.read() < 10);    //Wait until timer is larger than 10

led = 1;

There are many other options to implement this behavior. Also have a look at using https://mbed.org/handbook/Ticker or https://mbed.org/handbook/Timeout
