Blynk’s Slider to Control Intensity of a Bulb

Hi All,

I'm trying to build a WiFi controllable LED lamp using the Blynk's Vertical Slider.

Using a NodeMCU ESP8266, I can see the possibility to send an ON/OFF signal to a relay that can connect/disconnect the 220v signal.

But rather than the ON/OFF switch, I'd like to control the intensity using this fader.Could you anyone here suggest if there are any clues to accomplish this?

Thank you so much for taking the time to read :-)
