@will, yes I thought there should be something in there between the Arduino and relay. The relay is powered by the Arduino 5v, does not power the h...

The relay is not turning on/off. The serial monitor says it is. Wiring is ok this time, verified with relay only sketch.

ok thank you. in process of setting it all up.

@byron that is the same video I seen and made the decision to try the max6675.

Thank you very much! I will test it and let you know. I have most everything setup. Celsius is OK I know how to use a calculator. Lol
