This guide assumes that you've gotten your Raspberry Pi up and running, and have CircuitPython installed.

• If you have not done this yet, visit the installation guide here and come back when you're set up.

Installing Fonts

This project uses a Microsoft TrueType Font. To install it,enter the following into the terminal on your Raspberry Pi:

sudo apt-get install ttf-mscorefonts-installer

Installing CircuitPython Libraries

Since CircuitPython is running on the Raspberry Pi - installing the libraries for this guide is quick and easy.

To install the library for the display, enter the following into the terminal

sudo pip3 install adafruit-circuitpython-ssd1306

You'll also need toinstall the CircuitPython library to read data from the Analog Devices ADT7410: 

sudo pip3 install adafruit-circuitpython-adt7410

The code for this project is below.Save it to the Raspberry Pi asadafruit_io_adt7410.py

Before running the code, you'll need toset theADAFRUIT_IO_KEY to the Adafruit IO Key we saved earlier andset theADAFRUIT_IO_USERNAME to your Adafruit IO Username.

When both of these variables are changed, save the file. You canrun the program by entering the following in your terminal:

python adafruit_io_adt7410.py

and Press the Enter Key.

You should see the following print out in your terminal
