-For Windows you can just [download the released executable](https://github.com/Seal-Ammonia/Read-Sensor-Resistances/releases/download/beta/SeeDatResistance.exe) to use. For non-Windows systems you can just run `python test.py` and start from the UI. Enter the relevant information and start collect and measuring data. If you do not have a board avaliable, leave the dropdown menu in the UI as "no device" and it will run a simulation.

 ### develop & build
 Beside the c-based code for the Arduino board to read raw data from the board, everything has now been done in the python
 files. The main program is `test.py`, which calls `UI.py` to prompt for input. It is NOT recommended modifying the `ui.py`
