Circuit Builder

Interactive electronics learning platform with modular ES6+ architecture - hands-on STEM education through gamified circuit design

What It Does

Drag-and-drop circuit construction with real-time simulation. Build circuits, see them work, learn electronics principles through immediate feedback. From simple LED circuits to complex logic gates.

Learning Progression

Ages 8-10: Basic concepts - electricity flow, simple circuits with batteries and bulbs Ages 11-13: Circuit types - series, parallel, resistors, LEDs, measurements Ages 14-17: Advanced - logic gates, digital circuits, circuit analysis, Ohm’s law Ages 18+: Professional skills - PCB design, industry standards, certification prep

Game Mechanics

• Drag & Drop Interface - Intuitive component placement
• Real-time Simulation - Immediate feedback on circuit behavior
• Tutorial System - Progressive skill development with character guidance
• Challenges - Structured problems with increasing complexity
• Sandbox Mode - Free exploration and creative design
• Measurement Tools - Virtual multimeter and oscilloscope

Educational Features

Skill Tracking - Competency development across circuit concepts Achievement System - Recognition for milestones and creative solutions Portfolio - Collection of completed circuits and designs Character Guidance - AI mentors (Tortellini for technical, Sallie for organization)
