Describe the parts you are using and Codey Online draws a clear wiring diagram - which pin connects where - and writes the matching Arduino or ESP32 code to go with it.
Getting the wiring right is the scariest part of any project. Codey Online removes the guesswork: tell it "connect an HC-SR04, a servo and an OLED to an Arduino UNO" and it produces a clean connection diagram showing every pin, wire and power rail. Because the same AI writes the code, the diagram and the sketch always match.
Codey checks logic levels and power while it wires. It warns when a 5V sensor meets a 3.3V pin and suggests the fix. The diagram is built specifically for your board and components - not a generic template - so you can build the circuit with confidence and flash the firmware right away.
Diagrams tied to real components and real, compilable code.
Every wire maps to a real pin on your board and component, based on an indexed catalog of parts.
Codey flags 3.3V vs 5V mismatches and power problems before you connect anything.
The wiring and the sketch are generated together, so what you build matches what you flash.
Describe what you want to build. Codey Online writes the code, draws the wiring diagram, compiles it and flashes your board straight from the browser.
