sloth . do_action( 'stand' , 1 , 90 )
time . sleep( 1 )
if __name__ == "__main__" :
while True :
main()
How it works?
Instantiate various classes of
Music
,
Sloth
and
Ultrasonic
to be used.
music = Music()
sloth = Sloth([ 1 , 2 , 3 , 4 ])
sloth . set_offset([ 0 , 0 , 0 , 0 ])
sonar = Ultrasonic(Pin( "D2" ) ,Pin( "D3" ))
Here is the main program.
• Read the distance detected by the ultrasonic module and print it.
• When the distance is less than or equal to alert_distance (the threshold value set earlier, which is 20),
play the sound effect
talk3.wav
and move
backward
.
• When the
distance
is greater than
alert_distance
, PiSloth will Stand.
distance = sonar . read()
print (distance)
if distance <= alert_distance :
try :
music . sound_effect_threading( './sounds/talk3.wav' )
except Exception as e:
print (e)
sloth . do_action( 'backward' , 2 , 90 )
else :
sloth . do_action( 'stand' , 1 , 90 )
time . sleep( 1 )
Note:
You can add different sound effects or music to musics or sounds folder via Filezilla Software .
