Nano Embedded EEPROM Config Kit with Arduino Nano + HC-05
Nano Embedded EEPROM Config Kit: Store Settings From Phone Over BLE, Backed by Arduino Nano
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Most Arduino projects reset to defaults when you power them off—this one remembers. The Nano Embedded EEPROM Config Kit lets you build a compact device that accepts configuration over BLE from any phone, writes those settings to non‑volatile memory, and restores them exactly on the next boot. It’s an over‑the‑air configurator in Nano form factor, perfect for students exploring embedded systems that need reliable state storage without an SD card.
What You'll Build
You’ll assemble a self-contained unit inside an ABS enclosure. The 0.96in OLED shows current sensor readings (temperature/humidity from the DHT22) and the relay’s threshold value. Using a phone’s Bluetooth terminal, you can change that threshold or any parameter wirelessly, and the Nano instantly stores the new value in its EEPROM. Unplug the battery, wait an hour, power up again—the exact same settings appear. You’ve created a practical tool for IoT prototypes, home automation triggers, or college mini‑projects.
What You'll Learn
- Write and read configuration data to Arduino Nano’s internal EEPROM persistently across power cycles
- Establish bidirectional communication between HC‑05 Bluetooth module and a mobile phone
- Drive a 0.96in OLED display to show real‑time sensor values and user‑set parameters
- Control a 5V relay based on DHT22 readings and Bluetooth thresholds with zero‑lag decision logic

Who This Kit Is For
CBSE Class 11‑12 students working on computer science or physics investigatory projects will find the EEPROM persistence a rare add‑on that sets their work apart. B.Tech ECE/EEE first‑year learners at NITs, VIT, or state universities can use it for embedded systems lab assignments. Hackathon participants—Smart India Hackathon, ATL Tinkering Labs—get a ready‑to‑demo IoT configurator that shows sensor data and responds to remote commands without re‑flashing 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 inside the kit to launch the AI companion; it knows the exact wiring, code, and common pitfalls. You can also send a WhatsApp message to our support team for a personal check.
Do I need soldering experience?
Yes, basic soldering is required—the kit includes a soldering iron and solder wire, and the AI companion guides you through each joint on the PCB prototype boards.
Can this kit be powered without a battery?
While programming and testing, you can power the Nano via USB. The 9V battery snap is for standalone operation; the EEPROM retains settings regardless of power source.
Will my configuration settings be lost if I remove the battery?
No. EEPROM is non‑volatile memory—your thresholds and parameters stay intact for decades even with no power.
Nano saves configuration to EEPROM over BLE from phone. Settings persist power cycles. Compact OTA config.
