Build Your Own Component Identifier with Arduino Uno – Identify Resistors and Capacitors Instantly

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

Say goodbye to squinting at tiny resistor colour bands or guessing capacitor markings. With this kit, you will build a handheld Arduino-based tester that uses a precise voltage divider circuit to measure an unknown component. The measured value – whether in ohms or farads – appears clearly on a 16x2 LCD, turning your Arduino Uno into a reliable electronics bench tool you actually made yourself.

What You'll Build

You will assemble and program a practical component identifier tool. Insert an unknown resistor or capacitor using crocodile clips, and the Arduino’s ADC reads the voltage drop against a known reference. The on-board sketch then calculates and displays the component value on the bright LCD screen. You gain a useful instrument that stays on your workbench long after the build is finished.

What You'll Learn

• Read analog voltages using the Arduino Uno’s ADC pins
• Apply a voltage divider circuit to calculate unknown resistance
• Control a 16x2 LCD display via an I2C backpack for clean text output
• Assemble an electronics project on a breadboard without any soldering

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This project is crafted for CBSE Class 11-12 students who need to demonstrate practical measurement skills, ATL Tinkering Lab members building their own instruments, and young electronics enthusiasts aged 5-15. Even B.Tech first-year students find it a quick, satisfying way to revise ADC fundamentals. If you have ever struggled to read faded resistor stripes or needed a quick capacitor tester, this kit puts the solution in your hands.

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.
