Unfortunately, I don't know how to do it.

@Pezhvak Like that: https://github.com/taunoe/tauno-env-monitor/blob/master/Schematics/basic-leds.jpg

What baud rate do you use? Can you show me the code? Then I could try it myself and find the problem faster

Yes, you can show the full code.

When does the `Output` value changes? I commented out all the display stuff (I do not have it.) All I see is that it prints `255.oo` and this vale never...

When I run it, it works and plots the value [https://www.youtube.com/watch?v=_rHIS9uAH1s](https://www.youtube.com/watch?v=_rHIS9uAH1s)

What if you move the delay to the loop end? And try different values. Or a better way: get rid of it and also use millis() to update the display...

Does this work: ```c++ int analog_pin = A3; float analog_value = 0; unsigned int digital_value = 0; bool is_change = false; bool is_print = false; uint64_t prev_millis_print = 0; uint64_t...

Maybe PyQt5 is installed somewhat differently? If you install it: `pip3 install PyQt5`

Good news. Now it displays labels on the graph. Example Arduino code: ```c++ Serial.print("Label1"); Serial.print(data1); Serial.print("Label2"); Serial.print(data2); Serial.println(); ```
