Build a Real-Time Forearm EMG Visualizer 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.

Biofeedback systems start with a single muscle. This kit puts a working EMG capture and classification pipeline on your desk — one that reads your forearm signals, draws the envelope in real time on a crisp OLED, and lights up an LED the moment you flex. It’s the same signal chain used in prosthetics research and human-computer interaction, stripped down to its essentials so you can understand every component.

What You'll Build

By the end of the four-hour build, you’ll have a compact device that reads surface EMG through electrode patches, amplifies and filters the faint muscle impulses with the BioAmp Candy, then feeds an Arduino Uno running envelope detection. The OLED displays the live envelope trace and simultaneously classifies your forearm state — flex or rest — triggering an on‑board LED. It’s a complete, stand‑alone bio‑monitor you can wear or embed in a larger project.

What You'll Learn

• Capture surface electromyography (EMG) using medical‑grade dry electrode patches
• Amplify and band‑pass filter biological signals with the Muscle BioAmp Candy
• Program envelope detection and real‑time waveform display on a 0.96‑inch OLED
• Implement threshold‑based classification to reliably distinguish muscle flexion from rest

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Designed for intermediate makers who want to move beyond blinking LEDs. Ideal for CBSE Class 11–12 students exploring biomedical instrumentation, B.Tech ECE/EEE undergraduates building mini projects, and Smart India Hackathon teams prototyping human‑machine interfaces. ATL Tinkering Lab mentors and hobbyists at VIT, BITS, NIT or IIT campuses will find the classification logic especially useful as a foundation for gesture‑controlled wearables or assistive devices.

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.
