+- Currently can only use 5V as input voltage. May need to change the algorithm in `read_arduino.py`. Newer hardware will require 3.3V.
 - Should call `writerandomvalues.py` to simulate Arduino data when nothing is connected but user still want to run. Currently just pop up error
 - "plot" button is completely disabled, should be enabled whenever is not plotting but is reading data

 - [ ] Accept any inputs (such as resistor values, plot window size, base voltage etc.) as either command line argument or as input at beginning of program
 - [ ] Write random values to simulate a sensor if no sensor available (this feature might be removed in the future)
 - [ ] Advanced option menu in the UI to allow user to make more adjustments
+- [ ] Add resolution option in the UI to allow interchange between arduino (10bit) and esp32 (12 bits)
