Circuit Diagram Generator

Generate consistent, classroom-friendly wiring diagrams as code so they are reproducible, version-controlled, and easy to tweak. Every diagram is a small Python program that uses schemdraw to emit a PNG and an SVG.

The goal is a picture a beginner can follow with their finger: power comes in at the top, ground sits at the bottom, and each wire is color-coded by what it carries. Prioritize readability over schematic formality.

When to use this

Use it for any request like "draw the circuit for the X kit", "make a wiring diagram", "show how the parts connect", "update the schematic", or "add a hookup figure to the kit page". It targets microcontroller + peripheral projects (Pico, NeoPixel strips/rings, buttons, encoders, potentiometers, sensors, battery packs), but the house style works for any small DC circuit.
