variabili

X = 0
duration = 0
distance = 0

ciclo

SWITCH ON (5 Volt) switch on _trigger component
wait 10 milliseconds
SWITCH OFF   (0 Volt) switch off _trigger component
in the variable duration put the duration of the pulse on the pin: _receiver
the variable distanza is equal to the formula duration*0.1720
USB Arduino write on the serial: _distanza_(mm)= distanza
wait 100 milliseconds
the variable X is equal to the formula distance*10
USB Arduino write on the serial: _-_-_-_frequenza= X
PLAY the note di frequenza (XHz) duration: 100 milliseconds
