Build a 3-Channel ADC Voltage Logger with Raspberry Pi Pico

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

Imagine building your own data logger that reads three independent voltages every second, displays them on a bright OLED screen, and streams the numbers live to your computer. This kit turns three ordinary potentiometers into a rugged multi-channel analog monitoring station you can program and modify. Whether you’re measuring light levels, battery voltages, or sensor outputs, you’ll walk away with a reusable logging tool and the knowledge to scale it further.

What You'll Build

You’ll assemble a compact circuit on a breadboard where three 10kΩ potentiometers act as adjustable voltage sources. After uploading the provided MicroPython code, your Raspberry Pi Pico will convert their analog signals into decimal voltage values and show them on the 0.96-inch OLED. Simultaneously, it prints “Channel 1: 2.15V, Channel 2: 1.84V, Channel 3: 3.03V” every second to the serial console, giving you instant visual and logged feedback. The finished logger can be repurposed for any project that needs multi-channel data capture.

What You'll Learn

• Reading three ADC pins simultaneously and mapping raw values to real voltage readings
• Structuring Python code to loop and print sensor data at fixed intervals
• Interfacing a 0.96-inch OLED display via I2C to show live measurements
• Using potentiometers as variable voltage sources and understanding how analog input scaling works

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Students exploring CBSE Class 11–12 computer science or physics practicals will find the serial logging exercise closely aligned with their curriculum. B.Tech ECE and EEE freshers can use it as a no-solder mini project for fundamentals of embedded systems. ATL Tinkering Labs and hobby clubs will appreciate the plug-and-play setup that gets kids from age 10 upward logging real data within a single session.
