Pinlight: I was too lazy to read a 40-page datasheet, so I built an interactive electronics tutor
This is a submission for the Hacktoberfest Open-Source AI Challenge Week 3: Slow and Steady What I Built “Connect GPIO17 to the LED.” That sounds simple until you ask: which physical pin is GPIO17, where does ground go, and why is there a resistor in the diagram? I wanted those answers beside the board, with one small thing to do next. Pinlight is an interactive learning desk for electronics. It…
The author built Pinlight, an interactive electronics learning desk, to avoid the complexity of reading a 40-page datasheet. Pinlight combines a 3D board, guided activities, an AI tutor, and progress tracking into one workspace. The Raspberry Pi 5 and Arduino Uno R3 come with prepared lessons, while uploaded electronics PDFs are transformed into source-linked learning journeys.
Users can interact with the board, select components, and ask questions to receive explanations based on the lesson's sources. The tutor highlights relevant pins, connections, and control values, and allows users to rotate, zoom, and inspect the Raspberry Pi's 40-pin header. The workspace also includes reference code, source passages, learning notes, and a self-check before continuing.
Pinlight supports multiple languages, including English and Hindi, and uses voice-to-text and text-to-speech features. Users can sign in with Auth0 to keep their progress and saved items organized in their My desk. Pinlight aims to make starting electronics more approachable and help learners focus on understanding circuits rather than navigating multiple resources.
