Measure Galvanic Cell EMF with Arduino Uno – Build a Precision Electrochemical Series Plotter

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Ever wondered why a zinc-copper cell produces a different voltage than zinc-iron? With this kit, you'll build a high-precision EMF measurement system using an ADS1115 16-bit ADC and Arduino Uno, then automatically read and log voltages from multiple metal pair galvanic cells. The 16x2 LCD displays real-time voltage, and you can export data to plot the electrochemical series—turning a theoretical chemistry concept into a hands-on experiment that meets CBSE and STEM curriculum goals.

What You'll Build

A portable instrument that measures microvolt-level differences between two metal electrodes in salt solutions. After assembling the circuit on a breadboard and connecting the ADS1115 via I2C, you'll clip the electrode pairs, observe the EMF on the LCD, and record values to rank metals by their reduction potential. The result is a working scientific instrument and a clear visual plot of the electrochemical series.

What You'll Learn

• Interface a precision ADC (ADS1115) with Arduino over I2C to read analog voltages without noise
• Understand the electrochemical basis of galvanic cells and standard electrode potentials
• Program an LCD display for real-time voltage readout, making data logging intuitive
• Calibrate and validate analog measurements to compare theoretical vs. experimental EMF values
