Product information "BlinkyTree – Interactive LED Christmas Tree Soldering Kit"

The BlinkyTree is more than just a glowing decoration—it's an interactive electronics project that responds to you. With its ATtiny85 microcontroller as its “brain” and an electret microphone as its “ear,” this Christmas tree comes to life.

Features

Interactive control: A microphone detects when you blow on it and starts the music.
Background music: Plays 7 pre-programmed Christmas melodies.
Audio-reactive LEDs: The 13 LEDs dance in sync with the music and light up differently depending on the pitch.
Realistic candle flickering: A sophisticated algorithm simulates the gentle flickering of candlelight.
Completely open source: Firmware and documentation are freely available (CC-BY-NC 4.0).

How it works

After switching on, the BlinkyTree starts with a small animation in which the LED rings light up from bottom to top. The tree then switches to candle flicker mode, in which the LEDs light up in random, natural patterns.

The real fun begins when you blow hard into the microphone: the ATtiny85 recognizes the signal and starts one of the pre-programmed melodies. While the melody is playing, the tree lights up the LEDs to match the melody – high notes light up at the top, low notes at the base.
