This kit lets you build a timer that reads real-time clock data from a DS3231 module, toggles a relay to power grow lights at sunrise time, and turns them off at sunset time. An LCD screen displays the upcoming on\/off schedule so you always know what the system is doing. It’s a beginner-friendly introduction to smart farming automation.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eYou'll create a compact control unit that mounts next to your plant shelf. The Arduino reads the time from the DS3231 RTC and compares it with pre-set sunrise and sunset times. At the programmed moment, the relay switches your grow light on or off. A 16x2 LCD screen shows the next trigger time, and three tactile buttons let you adjust the schedule manually\n\n\u003c\/p\u003e\u003cdiv class=\"kit-description\"\u003e\n  \u003cp\u003eDS3231 RTC controls relay to switch grow light on at sunrise time and off at sunset time.
