Hi

What he has done is best termed an FLL approach. A PLL is indeed a possible solution. Even
with a FLL, he has quickly run into the fundamental problem of being able to measure the
result. Without that, he is dead in the water. Optimization is the key next step. To do that you
need data as you modify things.
