Artisanal setup ideal for chiptune
For Chiptune player Arduino Microbit I2C with MML
Product slightly better as described. Came in an enveloppe with a message from Michiel nicely handwritten on a piece of school paper.
It also came with a set of very stimulating problems e.g. learn a bit of Dutch to understand the code comments, figure out the pins from the previous versions, plug it to an ESP32 instead of an Arduino, figure out the code, get hilarious results => https://www.youtube.com/watch?v=wpMb5divrYw
I warmly recommend this kit to anyone willing to learn and play, it carries a very strong educational charge and is totally worth the bucks.
The documentation could be a bit more clear towards the different versions of the kit though.
