Arduino Logic Level Probe Kit – Debug Digital Circuits with 3 LEDs

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

Debugging digital circuits becomes visual and instant with a logic level probe. Whether you're troubleshooting a breadboard project, reversing an Arduino pin state, or teaching how logic levels work, this kit puts a functional probe in your hands in under three hours. The three LEDs—red, green, and yellow—light up for HIGH, LOW, and floating states on any digital pin.

What You'll Build

A portable, Arduino Uno-powered logic level probe that visually indicates the logic state of any digital pin. You'll have a handheld debugger with three clear LEDs: green for logic HIGH, red for logic LOW, and yellow when the pin is floating or disconnected. Built on a breadboard, it's easy to modify or integrate into larger projects.

What You'll Learn

• Reading digital input states from an Arduino pin
• Using pull-up and pull-down resistors to define floating pins
• Wiring LEDs with current-limiting resistors for safe operation
• Assembling a functional breadboard circuit from a schematic diagram

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Perfect for students in CBSE Class 6–10 exploring basic electronics, ATL Tinkering Lab beginners, and young hobbyists who want their first Arduino project. If you're helping a child understand how digital signals work—or building a debug tool for your own breadboard experiments—this kit skips the confusion and delivers a working probe fast.

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.
