[DUPLICATE] AC Dimmer blynk

hello blynkeři. I have Arduino Mega connected to Ethernet Shield. I would like to join the ac 4ch dimmers so that I could control it using blynk. (Http://m.ebay.com/itm/121752461158?_mwBanner=1) Do you have any tips, how to use the sketch? I would like to control the brightness of the spot light bulb, for example, 25, 50, 75, 100% I searched everywhere, but nowhere sketch for blynk. thanks to all for your help

@Honzin_Subrt just one thread at a time.

Are you familiar with the slider widget?

Lots of hits on this site if you search for “dimmer”.

It always amazes me how people think that another thread with same question will miraculously reach different people with “better” answers :stuck_out_tongue_winking_eye:

So thanks for the help gentlemen …
