Date and time based watering system using an Arduino and a RTC module

In this video I show you how to make an automated watering system based on a real time clock (RTC) module.
You can expand this project to control anything based on date/time, and you can add more switches, relays, etc.
For example, you can turn on and off your heater, lights, air purifier at a certain time of the day with this circuit.
