Talking Microbit with Human

The idea was to use the Micro:bit to record audio and interact with people in real time—just press Button A and let the magic happen. Building something that feels alive, even in a small way, has been such a thrill, and it’s awesome to see how a tiny device can handle sound and human input so seamlessly.

Here’s how it works: when I press Button A, the Micro:bit starts recording an audio clip at a sample rate I’ve set, capturing whatever I or someone else says. The code uses a serial write value to process the sound, storing it so it can play back later. It’s all about that human interaction—whether it’s me demoing it or someone else talking to it, the Micro:bit listens and responds. Watching it turn a quick “hello” into something I can hear again feels like I’ve given it a little voice of its own.

The future for this project is wide open, and I’m pumped to keep tinkering. I could add more buttons to save multiple clips or adjust the sample rate on the fly for different sound qualities. Maybe I’ll even make it recognize simple words and reply with pre-recorded responses, turning it into a mini chatbot. This mix of audio, coding, and human connection has me hooked, and I can’t wait to see how far I can push it!
