Things to Try on Your Own

This is a complex project with many different components. There are endless things you can do differently. Here are a few suggestions:

• Modify the program to allow turning the water on and off at multiple times in one day.
• Add the day of the week, and allow for different schedules on different days of the week.
• Add an LED indicating that no ON and OFF times have been set. Turn this LED on upon reset, and turn it off the first time a time is set. This is useful in case your Arduino loses power and resets, in which case it will forget any ON and OFF settings you made.
• Add a small LCD display to report the current time and settings
• A more advanced exercise: The RTC module we used has a tiny memory chip in it as well that will not forget when it loses power. You can research how to use this, and save the valve ON and OFF settings into that memory, so that in case the Arduino resets, you will still have the settings.
