#include "mbed.h"

//Use Cs random number generator rand(), but scaled and
//converted to a float (range 0.0 to 1.0) for PWM output
inline float random_number()

    return (rand()/(float(RAND_MAX)));
}

int main()

    while(1) {
//get a new random number for PWM
        myled = random_number();
//a bit slower time delay can be used for fire
