Setup Instructions

1. Download or clone the github repo to your computer.
2. Follow these instructions setup your NodeMCU.
3. In the Arduino IDE, install the following libraries:
   • Adafruit BMP3XX Library
   • Click on "Install All" to install all the dependencies
   • Adafruit IO Arduino
4. Flash the code in this repo onto the NodeMCU. You can do this by opening up ese_lab7_adafruit.ino in the ese218_lab7_adafruit folder.
5. Create an account at io.adafruit.
6. Click My Key
7. Going back to the Arduino IDE, modify config.h so it has the appropriate username and key.
8. Back to the io.adafruit.com website, click on Dashboard > Welcome Dashboard (or a new one that you made). Under the gear icon on the right hand side, select Create New Block > Line Chart.
   
9. Create a new feed called "pressure" (all lowercase). Select it and click "Next step >"
10. Create another Gauge block for the pressure feed.
11. Repeat steps 8-10 for a feed called "altitude".
12. Your final dashboard should look similar to the following:
13. In order to export data as a csv, follow these instructions.
