This kit lets you build a four-zone outdoor lighting scene controller that reads ambient lux via a BH1750 sensor, calculates sunrise and sunset times with a DS3231 real-time clock, and triggers relays for four independent lighting circuits. With an OLED status display and tactile buttons for on-the-fly override, you'll create a robust, field-ready system used in villa exteriors, farmhouses, and smart campuses.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eAn intelligent outdoor lighting system that controls four zones - porch lights, garden uplights, driveway accents, and facade washes - based on real-time daylight levels and solar time. The controller uses a sunrise offset to avoid nuisance triggering from clouds or artificial light. All zone statuses and live lux values are shown on the 0.96-inch OLED, and manual button overrides give you full control.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Learn\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eInterfacing I2C sensors (BH1750 lux, DS3231 RTC) with Arduino and reading data reliably\u003c\/li\u003e\n  \u003cli\u003eWriting embedded C code for real-time lighting decisions using light intensity thresholds and solar calendar calculations\u003c\/li\u003e\n  \u003cli\u003eUsing 4-channel relay modules to safely switch 12V outdoor lighting loads with flyback diode protection\u003c\/li\u003e\n  \u003cli\u003eIntegrating an OLED display to show live lux readings, RTC time, and zone status for field debugging\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eKit Contents\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eComponent\u003c\/th\u003e\n\u003cth\u003eQuantity\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eArduino Uno R3\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eBH1750\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDS3231 RTC\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e4-ch Relay Module\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e0.96in OLED\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eTactile Button\u003c\/td\u003e\n\u003ctd\u003e3\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e1N4007 Diode\u003c\/td\u003e\n\u003ctd\u003e5\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e10k?
