Build Your Own Stress-Busting Breathing 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.

You sit through an exam or a hackathon, heart racing, mind scrambling. Now imagine a soft chest belt that senses your breath and gently nudges your rhythm back to calm with a glowing LED and a soft tone. This kit lets you build that exact wearable — a biofeedback trainer that uses force-sensitive resistors to detect inhalation and exhalation, and an Arduino Nano to coach you into a 5‑second‑in, 5‑second‑out pattern proven to lower stress. No screen, no phone, just your own electronics quietly teaching you to breathe better.

What You'll Build

You'll assemble a comfortable elastic strap that hugs your chest and holds two FSR 402 sensors against your ribcage. As you breathe, the Arduino Nano reads the pressure changes, calculates your breathing rate, and drives an RGB LED and buzzer to signal inhale (green light, rising tone) and exhale (blue light, falling tone). By pacing your breaths to the cues, you train your nervous system for relaxed focus — a technique used by athletes, musicians, and students facing performance anxiety.

What You'll Learn

• Interfacing force-sensitive resistors with Arduino analog inputs to capture breath waveforms
• Translating analog sensor data into breathing phase detection using threshold logic
• Programming non-blocking timing loops with Arduino to synchronize LED color changes and buzzer pitch with respiration
• Building a wearable sensor system on a breadboard and securing electronics to fabric for body-mounted use

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit fits CBSE Class 11‑12 students crafting a psychology-backed science project, B.Tech ECE/EEE undergraduates exploring bio‑instrumentation, and ATL Tinkering Lab members prototyping a health wearable for the Smart India Hackathon. It’s also perfect for psychology enthusiasts or IIT/NIT aspirants who want to combine hardware with mental wellness — no medical background required, just an Arduino already in your toolkit.

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.
