Stop copy-pasting from old forum posts. Describe what your Arduino should do and Codey Online writes the code, explains it, fixes compile errors and flashes your board.
Programming an Arduino used to mean digging through documentation and forum threads. With Codey Online you just say what you want: "blink an LED when a button is pressed" or "log temperature to an SD card every minute". The AI writes clean Arduino C++, comments it so you learn, and repairs errors automatically until it compiles.
Real projects are more than code. Codey installs the libraries you need, generates the wiring diagram, checks the voltages and flashes the compiled sketch to your Arduino over USB. You go from an idea to a working device without ever leaving the browser.
From your first prompt to a board that runs your code.
Describe behaviour in plain words; get readable, commented Arduino code you can learn from.
Codey reads compiler output and fixes the sketch for you until it builds cleanly.
Server-side compilation and browser flashing get your program onto the board in one click.
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.
