Water saving unit


#1

I want to create a device that saves water but im very bad at coding. PLs help

How it works:

-the user will turn on the device with a switch. (switch)
-a different password is pressed to run different programming code (keypad)

  • the water will run for 5min before the solenoid valve shuts off. (solenoid valve)
  • 30 secs before the valve shuts, an LED will light up to indicate to the user that time is almost up. (LED)
  • the solenoid valve will turn on again after 30 secs for 1minute before shutting off again. ( should be in the loop section of programming?)
  • programme will reset when power is turned off

Hi epic,
I’d love to make this simple code for you but I’m really busy lately. Through the years or learning Arduino, I came across a great teacher. This guy explains Arduino in the best possible way. Just watch a few videos and I assure you that you’ll be able to code it yourself.
