Codey Online is developed by OTRONIC, a Netherlands-based electronics company. We are passionate about making hardware programming accessible to everyone, from students to professional engineers.
We noticed that many beginners struggle with the complexity of the traditional Arduino IDE, driver issues, and C++ syntax errors. We built Codey to bridge that gap using advanced Artificial Intelligence and modern Web Serial technology.
