Research Lab Kit 13: Cyclic Voltammetry Potentiostat on Arduino
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Unlock the fundamentals of electroanalytical chemistry by building a fully functional potentiostat circuit around an Arduino Nano. This kit enables you to perform cyclic voltammetry on laboratory samples, detecting glucose, pH changes, and heavy metal ions like lead or cadmium with precision instrumentation. Designed for advanced engineering and research lab courses, it replicates the core measurement chain of a commercial potentiostat at a fraction of the complexity.
What You'll Build
You will assemble a three-electrode potentiostat system with a Ag/AgCl reference electrode, platinum wire counter electrode, and an INA128-based transimpedance amplifier. The circuit, interfaced to an ADS1115 ADC, records current-voltage curves from test solutions in real time, displayed via Arduino serial monitor or Python script. This is the exact setup used in academic labs for sensor characterization.
What You'll Learn
- Design a precision analog front-end for low-current electrochemical signals
- Calibrate and interpret voltammetric peaks for quantitative analysis
- Implement data acquisition and signal processing on Arduino with high-resolution ADC
- Apply electrochemical principles to detect glucose, pH, and heavy metals in water samples

Who This Kit Is For
This advanced kit is purpose-built for B.Tech ECE, EEE, and instrumentation engineering students working on final-year projects on electrochemical sensors. It’s equally suited for M.Sc. chemistry and material science researchers who need a hands-on introduction to potentiostat design. Even teams at Smart India Hackathon hardware tracks or advanced ATL Tinkering Lab students aged 18+ will find the guided build an invaluable bridge between theory and lab-grade measurement.
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 included to access the AI companion trained on this exact kit. You can also reach us on WhatsApp for human support if needed.
Can I use this kit to detect other analytes besides glucose and heavy metals?
Yes. The potentiostat circuit is universal for redox-active species. You can modify the working electrode or electrolyte to measure ascorbic acid, dopamine, or any electroactive compound with a suitable potential window.
What is the minimum detectable concentration for heavy metal ions?
With proper electrode conditioning, the system can measure down to parts-per-million levels using the ADS1115's 16-bit resolution. For lower limits, you may need to implement stripping voltammetry in software.
Can I integrate this with Python or LabVIEW for automated data collection?
Absolutely. The Arduino streams raw ADC values over serial, which you can capture with Python (pyserial, matplotlib) for real-time plotting or data logging. Example scripts are provided in the build companion.
