When it senses +5v the program needs to begin monitoring and look for a series of events.....More than 4 hours of constant water flowAny Water flow after normal hours (ability to set the hours)
Do you really need e-mail/SMS/text
I just need to know how to make it send a message.
I am trying to detect on an analog pin when there is 3 vdc present and then when it is 0. That is the event I need to monitor.
