Need some help with my project Code.
we are Aiming for consistent timing with the Millis function when using Blynk, but as we use the Blynk we are getting additional second on timing.
we set the Timing for the relay to open for 1 min and close for 1 min as a trial but instead we get additional 10 seconds on the timing for both on and off.
please help badly wanted to graduate T_T
