Story

What if you constantly forget to shut off the water pump, or want to switch on the AC in your house 15 minutes before you get there. Or you want to feed your dog in the evening when you go out to party till the late night? This product allows them all.

Smart Fingers is a simple physical output to an electronic device that can do many things. Smart Fingers is controlled by a switch button in Cayenne.

Things you can do with the Smart Fingers

Switch off any outlet so anything electrical/electronic device becomes "on/off smart"

Feed your dog in the evening as you leave to party till the late night

Unlock a door and then lock it remotely (final video with the following extra items not done as of yet)

Water the plants remotely (or on a schedule) by constricting or releasing the water flow

Scare burglars by remotely setting off a chain reaction in your house when you're away and you're notified by a burglar alarm

Remote "jack in the box"

Alarm clock assist with water release/tip over

Etc. I'm sure many more can be thought of - though keep it to the non-violent side of things :)

  Cayenne.begin(token, ssid, password);
}
CAYENNE_IN(SERVO_VIRTUAL_PIN)
{
  // get value sent from dashboard
  double currentValue = getValue.asDouble();
  int position = currentValue * 200;
  // actually move the servo to the specified position
  s1.write(position);

  //update last position
  lastPosition = currentValue;
}



void loop() {
  
  Cayenne.run();
}
