Re: PWM output pin on reset


Put a 10-50K pullup resistor on the pins you want to stay high. When the device resets, there is not going to be any signal delivered on those pins, so you need to provide a default one.
You should choose a pin other than 12, which is a strapping pin that needs to be pulled low for 3V3 flash ...

0V means 100% power.
5V means 0% power.
problem is that every time the ESP resets, the pumps starts to work for a brief moment, as if the output pin went low during that time.
i have seen Espressif's 'ESP32 pin ...
