I'm trying to check if pin1 is either HIGH/LOW (so if a voltage is outputting from it) using Python. Later I plan on using this method to trigger a camera but I just want to check if the pin is HIGH/LOW.
I've looked around some forums but most of them are trying to read or transfer data (e.g., string) from Arduino to Python.
I've been trying to use pyserial but had no luck for this specific task.
I doubt you will get help on this forum, as the discussion almost exclusively concerns use of the Arduino IDE and C/C++.
If you are new to both Arduino and Python, you might reconsider your decision, as there are plenty of examples on line for other approaches to the simple project you have in mind. Or, head over to Adafruit and try CircuitPython with their boards.
