If I wire up a board like the attached, then do analogReference(EXTERNAL); and try and read the analog pin, it always comes back with 1023. If I use analogReference(INTERNAL); I get the appropriate values (16 or so for switch down, and 1023 for switch up). I'm going to be using an analog pin to also read a thermocouple and wheatstone bridge from a strain gauge, so I'd like them referenced to ground instead of 1.1v. Any idea what I'm doing wrong? This sure seems like it should be simple. Thank...🗓️ Mark your calendar from October 12, 2024 to October 12, 2024 at Theatre St. Denis. Aref is a celebration of passion, innovation, and community.
