Electro-Acupuncture Stimulator Kit with Arduino Mega + LED
Build a Clinical-Grade Electro-Acupuncture Stimulator with Arduino Mega and AD9833 DDS
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
This advanced electronics kit empowers you to construct a fully programmable TENS-style electro-acupuncture device. The Arduino Mega 2560 orchestrates an AD9833 direct digital synthesis module to produce tunable 1–100 Hz pulse trains, amplified by LM358 operational amplifiers to a safe 1–10 V amplitude for needle electrodes. Whether you are exploring non-pharmacological pain relief, muscle stimulation, or academic research in bioelectronics, you will have complete control over frequency, amplitude, and session logging.
What You'll Build
You will assemble a self-contained stimulator with an intuitive OLED interface, dual rotary encoders for parameter adjustment, and tactile buttons for mode selection. A DS3231 real-time clock stamps every session stored on a microSD card, enabling detailed analysis of stimulation patterns and therapy duration. The final unit slips into a compact enclosure, ready for benchtop use or experimental field trials.
What You'll Learn
- Generate sinusoidal and square-wave signals with micro-Hertz resolution using a DDS module
- Design dual-channel LM358 voltage amplification and passive current-limiting networks for body-safe output
- Build an encoder-driven OLED menu system on Arduino for real-time parameter control
- Implement timestamped data logging to microSD with an RTC for research-grade session documentation

Who This Kit Is For
This kit is intended for final-year B.Tech ECE/EEE students designing biomedical instrumentation projects, Smart India Hackathon teams prototyping therapeutic wearables, and independent researchers in physiotherapy investigating custom stimulation protocols. A strong foundation in Arduino programming, soldering, and basic analog circuit theory is expected.
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?

Is this device safe to use on the body?
Yes, the circuit limits output to a maximum of 10 V through 10kΩ resistors, delivering only micro-amperes of current, consistent with clinical TENS devices. However, always start at the lowest amplitude and never place electrodes on the chest, head, or broken skin without medical supervision.
Can I modify the pulse shape and frequency?
Absolutely. The Arduino firmware is open, allowing you to program any waveform pattern. The AD9833 DDS chip provides <1 Hz resolution over the 1–100 Hz range, and you can alter the LM358 gain stage to adjust output voltage.
Does this kit require a medical license to operate?
As an educational and experimental tool, no license is needed for personal research. If you intend to apply it therapeutically to others, consult local medical device regulations.
