Attach your p3 USB Power, cloudBit, Latch, Long LED and Wire to the mounting board (in that order).
Cut the wire in half, and connect the orange and red wires to trigger the relay switch.
Connect one wire from the 12v adaptor to the solenoid valve, and the other to the relay switch. Connect the other wire from the solenoid valve to the relay switch to complete the circuit.
House all the components in waterproof enclosure, then connect the solenoid valve to your tap and watering pipes, and power up the 12v adaptor and p3 USB power.
Visit IFTTT.com and use this recipe to turn your watering on; https://ifttt.com/recipes/202100-cloudbit-watering-on and this one to turn your watering off https://ifttt.com/recipes/202101-cloudbit-watering-off
Now all you need to do is create some calendar events on Google Calendar, one with the title ‘Watering ON’ and one with the title ‘Watering OFF’. The time between these calendar events will be the watering duration. Tip: IFTTT will trigger the cloud bit 15 minutes prior to the event time you specified.
Pour yourself an iced tea, sit back in a banana lounge and let the magic of the cloud do it’s thing!
