Design Rules
There's several rules when designing the indications that will make users understand the beeps and light flashes
more easily.
 The faster the buzzer beeps, the more emergent is.
 The faster the flight flashes, user should pay more attention for that situation.
 The RED light only light up when serious problem occurred.
