Greetings to all. Today I tried to work with ESP 32 for the first time by connecting PWM sg-90 to it, and I ran into the problem that the signal to the servo simply does not come out. I tried to re-connect pins and change pins in the code itself, but literally nothing helps. I tested this servo in parallel on an arduino uno, and it works. Perhaps I do not know any subtleties, or is it still a defective part?
My code:
>>> from machine import Pin, PWM
>>> pwm = PWM(Pin(15))
>>> pwm.duty(15)
>>> pwm.freq(50)
# ignores my actions
Full name of my ESP - ESP-WROOM-32. Help me please
