Group assignment:

Probe an input device’s analog levels and digital signals

Individual assignment

Measure something: add a sensor to a microcontroller board that you have designed and read it.

As input to my microcontroller I want to use Hall sensor to measure when cap will be closed or open

I chose between Honeywell SS543AT https://sensing.honeywell.com/SS543AT-unipolar and Murata AS-M15KA-R https://www.digikey.com/product-detail/en/murata-electronics/AS-M15KA-R/490-5758-2-ND/2757981

SS543AT in SOT-232 was chosen, because it have proper sizing

However, I did not find library for Hall sensor, and used different component with the same package type. So in schematic Hall sensor looks strange.

Then I milled the board

I started Javascript server to listen for input data, but no data is returned. Need to check this with oscillograph.
