Hello，
When using LM393, please confirm if it is OK?
1) Is there any limitation on the LM393 input current? Is there any problem with inputting 3mA into the input pin?
2) If the accessory circuit diagram, it can be understood as 3.3V through 1.5K resistor directly into the LM393 3 feet to see if there are any problems? Mcp4017 is a 10k sliding rheostat.
