Hey @mahmoodarslan1988 you said that you are controlling fan speed through blynk slider
So, can you give me more details about it . Because I am also tring for it
As I had already informed the prior user that you where questioning… please do NOT tack a “me too” onto another’s topic. I split your question out into your own topic.
However, a little searching will show you that controlling a fan (particularly an AC powered one) is really NOT a Blynk specific thing… Blynk would simply supply that range of setting via that slider… You then need particular hardware and code for all the rest.
Google for that and come back when you have it working from a simple potentiometer, then adding in Blynk is possible.
