ADAPTING A EXPAPLE PID LIBRARY FOR USE A THERMOCUPLE TYPE K + LCD 1602 SCREEN

Hi everyone!

I´,m started with Arduino UNO. And I need help.

I trying to make a PID temperature control with Arduino using an AC 230V/500W electric heating artefact controlled by a relay 5V / 2230V.

I actually have an LCD 1602 IC2 screen and a thermocouple type K MAX6675.

My problem is that I found a Arduino-PID-Library-master and a example named “PID_RelayOutput” that is wonderfull, but this code didn´t use my thermocouple and my screen.

Y have been trying to mix this simple code “PID_RelayOutput” with another code that use this thermocouple and this nos work (because I´m mechanic :frowning: )

Thanks
