NEW LEARN GUIDE: USB Morse Code Key with CircuitPython #CircuitPython #AdafruitLearningSystem @Adafruit

CircuitPython's TinyUSB library, which powers many of its USB features, just added support for USB audio types in version ten point three point zero alpha three. Adafruit's new learning guide demonstrates the capability with a hands-on project: building a USB Morse code key—a hardware device that connects to your computer and outputs code via USB. The example uses the library's new USB microphone capability to generate audio tones, making it a practical introduction to both Morse code and USB audio development on microcontrollers.
