I think I probably read my readings incorrectly. I was measuring some of the values from the MOSFET's drain instead of the project's common ground. The following readings are all measured from common ground. These values are probably a bit lower because the battery is starting to drain a bit.A: ON - 3.18 OFF - 3.18B: ON - 3.17 OFF - 3.17 (From the drain pin: + on pin, - on common ground)C: ON - 3.20 OFF - 0.06I'm confused on how I should measure B. Should I keep the - on the breadboard's common ground and the + on the drain pin? I'm confused because I thought the drain pin should be negative, sourced from ground.
