Sequence Target Tracker: A Powerful Browser-Based App for Visual Automation

Posted by Makermotor on May 20th 2025

Are you looking for a flexible, browser-based solution to automate target tracking with your Arduino projects? The MAKERMOTOR Sequence Target Tracker is a feature-rich web app designed to help hobbyists, educators, and developers create and manage visual tracking sequences using affordable hardware and intuitive software.

What Is the Sequence Target Tracker?

The Sequence Target Tracker is a web-based application that lets you define, configure, and execute sequences of visual targets using a webcam and MAKERMOTOR components. It’s ideal for automating tasks that require precise movement and tracking—such as robotics, pick-and-place systems, or interactive art installations. The app works directly in Chrome, Edge, Chromium, or Opera, and can be saved and run locally for offline use1.


Key Features

  • Multi-Target Tracking: Add and configure multiple colored targets in your webcam feed. Each target can have its own direction, speed, and stop threshold.

  • Sequence Configuration: Arrange targets in any order, set how many times to loop through the sequence, and save/load your custom setups for future use.

  • Advanced Camera Settings: Fine-tune color sensitivity and minimum size for reliable target detection—even in challenging lighting conditions.

  • Arduino Integration: Connect directly to an Arduino UNO (or compatible board) for real-time motor control, or use test mode for visual-only simulations.

  • User-Friendly Interface: Easily set up, preview, and manage your tracking sequence with a modern, intuitive UI.


How It Works

  1. Set Up Your Hardware:
    Connect your Arduino, motor controller (like an L298N), and DC motor following simple wiring instructions. Plug in a webcam to your computer.

  2. Configure in the Browser:
    Open the sequence_target_tracker.html file in a supported browser. Allow camera access, then click on objects in the video feed to create tracking targets.

  3. Customize Your Sequence:

    • Assign movement direction (clockwise/counter-clockwise) and speed for each target.

    • Set stop thresholds and pause times between targets.

    • Build your sequence by arranging target cards in the desired order.

  4. Run and Monitor:

    • Connect to your Arduino via the browser’s Web Serial API.

    • Start the sequence: The app will track each target in order, sending motor commands to your Arduino for precise movement.

    • Save your sequence with a snapshot for easy reloading later.


Ideal For

  • Robotics and Automation Projects

  • STEM Education and Demonstrations

  • DIY Pick-and-Place or Sorting Systems

  • Interactive Art and Installations


Open Source and Extensible

The Sequence Target Tracker is open source—encouraging customization, contribution, and sharing within the maker community. It’s provided “as is” for educational and experimental use, so you can adapt it for your unique needs while following best engineering practices1.
