I have something to implement and I am looking for the best way to do it. What I want: Using a blynk slider I will pass an int to a variable like how many seconds a relay will be on, activated. If the user press a start button then using a blynk timer ( simpletimer ) will be activated this relay on for the specified time and then off.
I am in trouble how to setup and call the timer.
Can you help me?
Thanks and Best Regards,
