Hi thx for the reply ,I connect in D6 position of board . If I touch sensor I get 3.6v in D6 is working this part. The pwm part other pin is not working I see D4 have constant voltage that's the reason I get activatio of buzzer when I poweron. I changed program to use another port and nothing. Apprenñy pwm in WeMos is different, is like Made via software not hardware . Regards
