Biofeedback Stress Therapy Device Kit with Arduino Nano + Sensor
Biofeedback Stress Therapy Device Kit: Build a Wearable HRV Trainer with 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.
Chronic stress is a silent epidemic on Indian campuses. This kit lets you build a personal biofeedback wearable that reads your electrodermal activity (GSR) — a real-time stress indicator — and then guides you through paced breathing with a soothing RGB LED animation, training your heart rate variability (HRV) for lasting calm.
What You'll Build
A wrist-worn device that detects when your stress spikes via galvanic skin response, triggers a vibration alert, and displays a breathing pacer on the OLED screen. It uses three RGB LEDs to create a wave of color that expands and contracts, helping you synchronize your inhalation and exhalation.
What You'll Learn
- Interface a GSR sensor to Arduino Nano and filter raw signals for reliable stress detection.
- Program non-blocking LED animations using PWM to create a breathing guide that fades smoothly.
- Control a coin vibration motor for haptic feedback using a transistor and diode protection.
- Integrate an OLED display to show real-time stress levels and session metrics.

Who This Kit Is For
This advanced kit is built for B.Tech ECE/EEE and biomedical engineering students tackling health-tech projects for Smart India Hackathon or final year capstones. It’s also ideal for NCC cadets and research interns at IITs, NITs, and VIT exploring wearable stress interventions.
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?
The AI companion provides instant, context-aware help; if you still need human support, message us on WhatsApp for a direct engineer chat.
Can I use this kit to collect data for a research study?
Yes, the GSR sensor outputs analog data; you can log it via serial and analyze HRV patterns. The companion will guide you through data extraction.
Do I need prior experience with biosensors?
This is an advanced kit; familiarity with Arduino coding and basic sensor interfacing is assumed. The AI companion provides code walkthroughs, but you should understand signal filtering concepts.
How long does the battery last?
The 500mAh LiPo powers the device for approximately 4-5 hours of continuous monitoring and breathing sessions, rechargeable via micro-USB using the TP4056 module.
GSR sensor reads stress level. Guided breathing LED animation paces inhalation and exhalation for HRV training.
