A button and slider at same digital pin on Adafruit ESP8266

[engineeringtcpi1]

What I have: Blynk, Adafruit Feather Huzzah ESP8266.

What I need: Use Slider and Botton to control a same digital pin.

I am working on a project and I need the PWM signal from the slider to do a dimming function. Meanwhile I need the ON/OFF to do a switch function. I am using a specific digital port, ex. GP15 and this pin on the ESP8266 is tied to my main driver. I can’t do them both because once this specific port is token, I can only control one of these two functions, either ON/OFF or PWM. Is there any other way in the codes wise that I can control both of these two functions together and I only have to connect to a exact same digital pin?

Study virtual pins in the docs, they can control thousands of physical pins if you have that many.

You could try something like a current flow detection device, or this one. No need for the value of the current, just whether it is on or off should be sufficient. Then using that logical on/off determination show the activity in the app with the Blynk.virtualWrite() as @Dmitriy mentioned. I have done something similar (without the active hardware detection) using an app slider and a single physical button/switch combo to control the brightness of an LED #define WLED 6 // Set Physical LED p…

It is not exactly what you are looking for, examples rarely are… so study it and tweak it to your needs.
