a can someone please help?
im trying to make a backup beeper with lights
it would have a ultrasonic rangefinder, and if you got closer, a beeper would go
beep, beep, beep, beep, and show a yellow led
if you got even closer, abeeper would go
beeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeep, and show a red led
if you were far enough away, it would go silent, and show a green led.
(also on a pi-topPROTO+)
