Arduino code for TUFF DOS payload for the Balloon Payload Program at the University of Maryland. The payload reads tension data from the rope in atmospheric balloon launches (>50,000 ft).

Code by Jeremy Kuznetsov, Jim Oliver Villegas, Jaxon Lee, Malcolm Maas, and Daniel Grammer.

sudo snap install arduino

OR...

1. Download Arduino IDE
2. Download TUFF_Flight_Data_Collector.ino (or copy paste)
3. Run TUFF_Flight_Data_Collector.ino with payload hanging load free
4. You're ready to launch!

Note: Run TUFF_calibration with its experiment procedure for more accurate readings

The code is broken up as follows:

• 📁Data Analysis: Python Juypter Notebook analysis of TUFF data
  • 📁Data: All data collected across our 4 flights. Includes formatted and unformatted data
  • 🏃*.py: Files with analysis. Run them to see graphs of our data
• 🏃Launch_Day_Tester/Launch_Day_Tester.ino: Extra file to put various tests in
• 🏃TUFF_Calibrator/TUFF_Calibrator.ino: Gets calibration value for tension sensor. See file for details
• 🏃TUFF_Flight_Data_Collector/TUFF_Flight_Data_Collector.ino: Collects data during flight and writes to an SD card
