hi
i just purchased the pan tilt hat. i know it works because i tried the python examples.
But how can i get ARC to recognize it?
I do have the ez server installed on the rpi with a camera, it connects, i tried the camera control example and the video works. i added the vertical servo, tried to set it up as D0, D1 and D2. neither will control the pan and tilt hat. i believe the pan and tilt works of of i2C but i am not certain.
information on the pan and tilt hat can be found at http://pimoroni.com/pantilthat
please help, Thank you in advance.

fyi, i just tried to run both in the same terminal session, and i received the same error.
i install pyaudio, i now received the following error

There is an issue with Buster and portaudio library you will need to edit your shell script:
add the following line to the end:
you can reboot or reload the shell (previous changes):
if you want audio through the audio jack:

i did make the changes as you illustrated. i also just for fun added a horiz servo. tried D0 and D1- as expected the servo did not respond. also just wanted to say thanks for your effort!
can i connect the servo directly to the rpi?
if yes which gpio pin coresponds to D0?
