Motor Driver Tester Kit – Verify L298N & L9110 Boards with Arduino and LED Indicators

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

After building a robot or automation project, the last thing you want is a faulty motor driver board that takes hours to debug. This kit lets you assemble a dedicated tester that plugs into any L298N or L9110 module and instantly reveals the direction and PWM strength on LED indicators for each channel. No multimeter poking, no guessing—just a quick, repeatable check that saves project time and frustration.

What You'll Build

You'll construct a stand-alone motor driver diagnostic tool using an Arduino Uno, two potentiometers to adjust speed and direction, and an array of LEDs that light up to show which motor output is active and how strong the PWM signal is. Press the tactile buttons to toggle test modes—continuous rotation, step direction change, or manual control. Once built, you have a bench instrument you’ll use on every robotics build to verify your motor controllers before wiring them to expensive motors.

What You'll Learn

• Map Arduino analog inputs from potentiometers to control motor speed and direction
• Read push-button inputs to cycle through test modes and trigger single-step direction changes
• Understand the logic-level signals (IN1–IN4, ENA/ENB) that drive L298N and L9110 modules
• Design LED indicators that visually communicate PWM duty cycle and motor rotation direction

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Ideal for young electronics explorers (10+ with adult help) and serious makers alike. CBSE Class 11–12 students testing motor drivers for their robotics elective, B.Tech ECE/EEE students verifying L298N boards in their mini-projects, and ATL Tinkering Lab facilitators who need a quick sanity-check tool will all find this kit valuable. Smart India Hackathon teams can use it to eliminate motor control bugs before the final run.

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.
