Context:  The normal state is that a man sitting back to people,

if you touch his shoulder(touch sensor), he will turn around.And a green led will be on;

if you talk to him(sound sensor can sense), it will turn on his heart(red led on);

if you don’t talk to him for 8 seconds, he will turn back, and the green led will be off.
