Rotary Encoder Menu UI Framework Kit with Arduino Uno + LED
Rotary Encoder Menu UI Framework Kit — Build a Reusable Navigation System with Arduino Uno + OLED
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine a single knob that scrolls through crisp OLED menus, launches sensor readings, and toggles a relay with a long press — then instantly reuse that same interface code in your next ten projects. This kit delivers exactly that: a rotary-encoder-driven, multi-level menu UI framework that becomes your go-to library for any Arduino build needing a display. Designed for advanced learners, it moves beyond blinking LEDs into state-machine logic, interrupt handling, and clean, portable code architecture.
What You'll Build
You'll assemble and program a complete control panel: a 0.96-inch OLED shows a hierarchical menu with items for temperature, humidity, and relay control. Turn the rotary encoder to scroll, short-press to enter a submenu or trigger an action, long-press to go back. The DHT22 sensor feeds live environmental data, while the relay module drives a load — giving you a real-world UI platform ready to adapt for home automation, lab instruments, or robotics.
What You'll Learn
- Rotary encoder decoding with hardware interrupts for responsive, glitch‑free input
- OLED graphics programming using U8g2 library to render menus, values, and status icons
- State machine design to manage multi-level menu navigation and mode switching
- Integrating DHT22 sensor data into the menu, with live display and health checks
- Relay control through the menu — learn hardware abstraction so your UI drives outputs
- Soldering and PCB assembly to transform breadboard prototypes into a stable hardware module

Who This Kit Is For
B.Tech ECE/EEE students in their 3rd or 4th year will find this kit ideal for mini-projects or final-year displays. It’s also perfect for Smart India Hackathon hardware track participants who need a dependable menu library under tight deadlines. Makers from IIT, NIT, VIT, BITS Pilani, or ATL Tinkering Lab mentors will appreciate the scaffolded code that shortens embedded UI development from days to hours.
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?
Open the AI companion from the QR code for instant troubleshooting, or drop a WhatsApp message — we’ll help you decipher error logs or soldering snags.
Can I reuse the menu code for other sensors or LCDs?
Absolutely. The framework separates UI logic from hardware drivers: swap the DHT22 for an MPU6050 or change the OLED for an LCD with minimal modifications.
I’m new to soldering — will I damage the board?
The PCB prototype board is forgiving, and the AI guide shows iron temperature and technique. Practice on spare resistor leads first; we’ve included extra components just in case.
How do I power the project without a USB cable?
The 9V battery snap lets you run the Arduino stand‑alone. The relay module remains isolated, so you can safely switch small appliances via the menu.
Rotary encoder navigates multi-level OLED menu. Long press enters, short press scrolls. Reusable UI code.
