Vertical Farm LED Spectrum Controller Kit with Arduino Uno + LED
Advanced Vertical Farm LED Spectrum Controller with Arduino Uno — Precision PPFD, PWM & RTC Photoperiod Control
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
In vertical farming, light spectrum and photoperiod directly dictate crop morphology, biomass, and secondary metabolite production. 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.
What You'll Build
You’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. After soldering the MOSFET drivers and sensor circuits, you’ll calibrate output using the BH1750 lux readings and upload code that runs timed photoperiods automatically.
What You'll Learn
- Design and wire high-current MOSFET LED drivers for safe, flicker-free PWM dimming
- Interface I2C sensors (BH1750 light sensor, DS3231 RTC) and OLED display with Arduino Uno
- Program an automatic photoperiod controller using RTC alarms to switch light recipes at sunrise/sunset
- Calibrate LED spectrum output to approximate target PPFD values for different plant growth stages

Who This Kit Is For
B.Tech ECE and EEE students building IoT-based vertical farming prototypes for Smart India Hackathon or final-year projects will find every component pre-selected for real agricultural loads. Agri-tech startup engineers testing spectrum recipes for microgreens or medicinal crops can iterate faster without sourcing individual drivers. Makers at tinkering labs or ATL mentors guiding advanced workshops on controlled environment agriculture will appreciate the plug-and-play parts list and RTC sample code.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code to open the AI companion, which can diagnose issues step by step. You can also send photos via WhatsApp to our support team for direct troubleshooting.
Can I customize the LED spectrum for specific crops like basil or lettuce?
Yes, the PWM channels let you fine-tune intensity ratios for red, blue, and white independently. The AI companion includes guides on mapping duty cycles to common PPFD recipes from published horticulture studies.
Is the software code included?
Absolutely. The QR code links to pre-written Arduino sketches for photoperiod control, BH1750 reading, and OLED display. You can modify and extend the open-source code hosted on Compoden’s GitHub repository.
What if I want to add more LED channels or sensors later?
The Arduino Uno has spare digital and analog pins. The AI companion can suggest pin assignments and provide wiring diagrams for adding UV or far-red strips using the spare MOSFETs and gate resistors included in the kit.
Controls separate red, blue and white LED channels via PWM to deliver ideal PPFD spectrum. RTC sets photoperiod.
