Zero crossing pin #214

Closed Yousefff1 closed 5 years ago

Yousefff1 commented 5 years ago

I am trying to use sonoff-basic-pwm with an AC dimming module, on the module there are 4 pins, VCC, GND, Zero Crossing and PWM

Using the sketch and flashing it to a nodemcu, I was able to dim the onboard LED, my question is:

Where to connect the Zero Crossing pin from the module to the Nodemcu?

The link for the AC dimming module https://robotdyn.com/ac-light-dimmer-module-1-channel-3-3v-5v-logic-ac-50-60hz-220v-110v.html

Thank you,

You need difference driver. Example ne555 timer or mcu ”microchip, atmel...” http://sound.whsites.net/project157.htm

Esp8266 it is not possible to drive time critical process”zero cross detect”

This is my project: https://github.com/jukorp?tab=projects Time critical mcu is pic16lf15313 mcu convert uart data and zero cross to mosfet.

555 timer is simplest
