CubeSat Testing Device

Arduino folder contains .ino sketches

Python folder contains .py files

Arduino Libraries Used:

1. bodge's HX711 library

Python Libraries Required:

1. Tkinter
2. pySerial
3. Matplotlib
4. numpy

Calibration Instruction

Load Cell Calibration

1. Build and upload Calibration.ino sketch onto the arduino UNO
2. Connect the load cell and amplifiers as described in the comments
3. Open the serial monitor and add a known weight onto the load cell
4. If it's not accurate, change the set_scale(value) until it does become accurate
5. This value is calculated by using set_scale() with no parameters, taking the output and dividing it by the known weight
6. Replace the value, performing trial and error till it's accurate and repeat for each load cell

Build Instructions:

1. Ensure the required libraries are preinstalled
2. Compile and Upload the ArduinoCTD.ino sketch
3. Build and run the mergedBuild.py file to open the GUI

EXE build Instructions

1. cx_Freeze required
2. In the setup.py file, modify the directory of the includeFiles for your machine.
3. run python setup.py build in the command line window of the directory
4. Open the build folder created and run mergedBuild.exe
