Duino Code Generator is an AI-powered tool that generates Arduino code from natural language prompts. By leveraging OpenAI's GPT-3.5-turbo model, it translates user descriptions into working code for various Arduino boards such as Nano, Uno, and Mega, and supports sensors like DS18B20 and actuators like LCD screens and water pumps. The tool provides best practice guidelines to help users craft effective prompts: be specific about components, break complex tasks into smaller steps, and test and refine inputs. It also offers examples of good and bad prompts to illustrate the expected level of detail. All generated code must be reviewed and tested before uploading to hardware devices to ensure safety and correctness.
