Hi!
I have similar problem but with Grove - PIR Motion Sensor. I’ve followed the instructions above, but instead of the last tep, I did:
python grove_mini_pir_motion_sensor.py 12
the result is nothing - no error, no return of any values. I’m also not sure that mini pir is correct choice since i have a regular pir motion sensor.
UPDATE: when I run ultrasonic ranger - I start to receive some output, with worning that it is incorrect. (Obviously, since I plugged motion sensor).
Best regards,
Andrei
