Rename the uncompressed folder Adafruit_MAX31865 and check that the Adafruit_MAX31865 folder contains

Adafruit_MAX31865.cpp and Adafruit_MAX31865.h

Place the Adafruit_MAX31865 library folder your arduinosketchfolder/libraries/ folder.

You may need to create the libraries subfolder if its your first library. Restart the IDE.

We also have a great tutorial on Arduino library installation at:

http://learn.adafruit.com/adafruit-all-about-arduino-libraries-install-use (https://adafru.it/aYM)

Restart the IDE

Attach PT100 or PT1000 RTD

You'll need to attach an RTD, for this demo we'll be using a 3-wire 1 meter long one but you can adjust the demo if you

have a 2 or 4 wire. Check the RTD wiring page for the jumpers and wiring requirements!

Load Demo

Open up File->Examples->Adafruit_MAX31865->max31865 and upload to your Arduino wired up to the sensor. Adjust

the max.begin(MAX31865_3WIRE) line if necessary.
