    Hello, I need a code that when talk to google or Alexa will be able to dim the GPIO (PWM) so I could connect to MOC and triac fro 110vac Or 220vac 50/60hz. The code should be to turn ON/OFF 2 GPIOS, DIM 2 GPIOS level. For example if say Google or alexa Dim lights to 10% - 100% it should drop to that level, and/or if say just turn OFF/ON should
