Digital Capacitor Meter Kit with Arduino Uno – Build a Reliable Capacitor Tester

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

Turn your Arduino Uno into a professional-grade capacitance meter. Using the RC charge time method, this kit measures capacitor values from 1nF to 1000µF and displays the result clearly on a 16x2 LCD. Whether you’re sorting a mixed bag of capacitors or verifying value before soldering, this meter saves time and eliminates guesswork.

What You'll Build

You’ll assemble a standalone digital capacitor meter with crocodile clip test leads for hands‑free measurement. The large LCD instantly shows the capacitor value in nanofarads or microfarads, automatically switching units as needed. Power it with a 9V battery and you have a portable tool that lives on your workbench or in your field repair bag.

What You'll Learn

• How to wire an I2C backpack to a 16x2 LCD for crisp text readout
• Using Arduino to measure time constants as a capacitor charges
• Converting raw time data into accurate farad values with code calibration
• Building a rugged, repeatable testing instrument on a breadboard

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

CBSE Class 11‑12 students exploring RC circuits in their physics practicals find this meter a hands‑on upgrade. B.Tech ECE/EEE first‑years at IIT, NIT, VIT or BITS use it to learn Arduino‑based instrumentation. Makers in ATL tinkering labs and electronics hobbyists across India rely on it as a quick capacitor checker on the bench.

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.
