This kit lets you build a professional-grade controller that individually drives red, blue, and white LED strips via MOSFET PWM, using a BH1750 ambient light sensor for feedback and a DS3231 real-time clock to automate day\/night cycles. It’s the bridge between maker-level Arduino skills and production-ready CEA research.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eYou’ll assemble and program an LED spectrum controller that can independently dim three colour channels to achieve specific PPFD ratios for vegetative or flowering stages. The OLED displays real-time light intensity and schedule status, while three tactile buttons let you manually override channels or set parameters.
