This is a personnal project. It's a kind of stand-alone launchpad that lets you to play music samples with buttons. The main components of this embaded system are an arduino nano and an audio amplifier. I did the code, electronics and design from scratch. This is the project that I am currently doing. I used TMRpcm library for the firmware and various small modules for the electronic circuit. This project will evolve to soon integrate new features like microphone recording.
