Thanks, that helps a lot. This is my first use of the Unit devices. I've use the HAT on the M5
which obviously is only 1 at a time.
I'll get the PbHUB and the I2C version of the Ultrasonic Distance Unit.
I'm working on many sensors to help disabled users. These sensors help those in
wheelchairs where they might not be able to even touch buttons. So providing a multitude
of options (motion, tilt, distance, LUX, buttons) - even the touch of the Core2 is very sensitive
which is good.
Thanks,
