I added potentiometer for R1, R2 which adjusts my "zero point" above which the diode starts to light.
In the class i will put this circuit together on breadboard with MCP9700 temperatuere sensor, right now im just testing the circuits on simulator.

Do i need to change anything more for this circuit for the first part? (potentiometer part)
