Problem with Code to Open Solenoids

@ruilviana

pulseDuration = pulseIn(INJECTOR_PIN, HIGH);
    pulseFrequency = 60000 / pulseDuration; // Frequency in minutes
    pulseProduct = pulseDuration * pulseFrequency;

This part of your code is blocking nano.
See in the simulator.
" Nano_seensor - Wokwi ESP32, STM32, Arduino Simulator

With this part released, it does not print on the serial,
but with this part commented,
the value read from the potentiometer (simulating the sensor) appears on the serial.

Run the simulator with the part released and then comment on the part and run it again.
and vary the potentiometer value.

You thinks it block the whole Nano? I'm not testing injector code yet, but maybe it doesn't matter.
Ah I start to see now. Maybe the code can not run. Very smart. I didn't see that possibility.
Thank you

Serial.print()ing

Yes that makes sense.
I never used the serial printer yet, so it's a good time to learn.
Thanks.
