About Circuit Hub

Circuit Hub started with a simple frustration: great electronics content was scattered across forums, repos, and video playlists, while simulation tools lived on their own. We built a single place where you can discover a project, follow a clear build guide, and validate your wiring in a live lab before you touch a breadboard.

Today, more than 50,000 makers use Circuit Hub to learn Arduino, ESP32, Raspberry Pi, and IoT workflows. Whether you are soldering your first LED or shipping a connected product, our library is designed to meet you where you are and help you move forward with confidence.

• Curated project library — Real-world builds with parts lists, wiring notes, firmware hints, and difficulty ratings so you can pick the right challenge.
• Hands-on tutorials — Structured learning paths that explain concepts, not just copy-paste steps.
• Live Wokwi labs — Embedded simulations so you can test logic and connections before ordering components.
• Community submissions — Makers can share their own builds through our project submission flow, keeping the catalog fresh and diverse.

Hardware should be approachable, reproducible, and safe to experiment with. We lower the barrier to entry by pairing clear documentation with tools that reduce costly mistakes — so more people can learn electronics, contribute open knowledge, and ship projects they are proud of.

• Learn by building — Theory matters, but retention comes from doing.
• Open by default — Schematics, code, and write-ups should be easy to fork, adapt, and improve.
• Quality over quantity — Every project we feature should be accurate, tested where possible, and honest about limitations.
• Privacy-first — We collect only what we need to run the service. Read our Privacy Policy for details.

Circuit Hub is maintained by a small team of engineers, educators, and hardware enthusiasts based in India. We work with contributors worldwide — from students sharing class projects to professionals documenting production prototypes — to keep content practical and up to date.

We are independent and community-driven. We do not sell your data, and we are transparent about how the platform works in our Terms of Service.

There are many ways to participate:

• Share a project — Document your build and publish it via Submit Project.
• Report issues — Found incorrect wiring, broken links, or outdated firmware? Let us know through Contact.
• Spread the word — Star us on GitHub, join community channels linked in the footer, or subscribe to the newsletter for weekly project picks.
