Well I want to know if there is an input button or feature with in blynk to add this command? I’m not a coder so I’ve managed to get the pumps running on, on off button along with timers and speed control, but if I wanted to add this command function how would I do it? Excuse my ignorance
This is a basic microcontroller question, and not related to Blynk in any way.
Do some research about connecting switches to GPIO pins on whatever type of board you are using. Go for a solution which uses a timer to ‘poll’ the pins on a regular basis to see if the switch is open or closed.
