/** class to make control LED on/off fashion using GPIO
 *   The class use a timer to change led on/off  - it is not blocking while scheduling led on/off
 *
 * Example:
 * @code
 * #include "mbed.h"
 * #include "Led.h"
 * 
 * Led led(LED1);
 * 
 *#define schedule_num   7
 *float toggle[schedule_num] = {1, 1, 1, 0, 1, 0, 1};

 * int main() {
 *       ...
 *   led.simpleBlink(0.5);   //turn on led for 0.5 second    
 *       ...
 *   led.toggleLed(toggle, schedule_num, 0.5);    //change led to on or off every 0.5 second
 *       ...
 * }
 * @endcode
