You can use the watch-node to check the values from the different number pins. Analog read node gives values from 0 - 1. So if you want to compare values above 1 you have to map the source range (0 - 1) to the target range (e. g. 0 - 10, 0 - 1023, 50 - 80 etc.) with the map-range node. There is also a map-clip-range node clipping values below or above the selected range to the limited range.
