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.
