- by using Eric IDE
Read out the value of the potentiometer from Arduino Port A0 over the RS232 to the Python Program.
Download the Arduino program and upload this example to your Arduino UNO.
Then download the folder Program and unzip it on your computer.
Check the com-port number from Arduino. You can start the main.py program for the first test.
If you want to edit the program, I recommended to install the IDE Eric first.
