  Architecture Diagram

Inspiration

Watching beginners stall on the first mile—IDE installs, wiring guesswork, wrong resistor values. We wanted “describe it → get working code + circuit” so more people actually build and learn electronics

What it does

Turns plain-English prompts into Arduino code and a Wokwi-ready diagram.json, with basic safety checks (polarity, resistor sizing) and an optional live run in the browser.

How I built it

Stack & architecture

• AWS Bedrock (Claude family) for planning, code gen, and diagram synthesis.
• Strands Agents to orchestrate two specialists:
• Circuit Designer → structured diagram.json
• Arduino Programmer → sketch.ino
• AWS Bedrock AgentCore to package and deploy the agent runtime.
• Nova Act for live browser actions (useful for Wokwi/Tinkercad flows and verification).
• Wokwi as the simulation target for instant feedback.

Workflow

1. Natural-language prompt → planning step (components, pins, safety checks).
2. Circuit Designer emits diagram.json (schema-validated).
3. Arduino Programmer emits Arduino code (compiles & runs in Wokwi).
4. Nova Act opens Wokwi, pastes artifacts, and runs the sim.
5. Return artifacts + whether the simulation works or not.

Challenges I ran into

• Getting deterministic, correct pin mappings and grounds in diagram.json
• Handling browser automation quirks (logins, timing, copy & paste)
• Live View for web deployment

Accomplishments that I'm proud of

• Able to use AI for creating and simulating electronic circuit

What I learned

• Structured output formatting is crucial for agentic workflow
• Human-in-the-loop helps in agentic AI use cases

What’s Next

• Web application with live view of circuit building and simulation
• Fine-tune the model to enable the creation of more complex circuits
• Work with other simulation software such as circuitjs and fritzing
