Algorithmic Composition Engine Kit: Build a Markov Chain Melody Generator with Arduino Mega

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

This kit guides you through building an algorithmic composition engine that generates endless original melodies using a Markov chain model running on an Arduino Mega. Each tune is played back through a DFPlayer sample system, turning a prototyping board into a hands-on exploration of generative music and computational creativity. By the end, you’ll have a standalone instrument that composes in real-time, reacting to your physical controls.

What You'll Build

You'll assemble a device that continuously creates melodies via weighted probability transitions between musical notes. Two rotary encoders let you adjust the Markov chain parameters and scroll through visualizations on the OLED display. The PAM8403 amplifier and 3W speaker deliver clear sample playback, while the enclosure houses everything in a polished, portable form. No two performances are ever the same.

What You'll Learn

• Implement a Markov chain algorithm on Arduino Mega for real-time note generation
• Interface the DFPlayer Mini module to trigger WAV samples from a MicroSD card
• Design a user interface with rotary encoders and a 0.96-inch OLED display
• Integrate audio amplification using the PAM8403 and match speaker impedance
