Bluetooth page turner

So I just got myself an iPad Pro, mainly to read sheet music from it. The first thing that comes to mind when using a tablet to read music is: "How do I turn pages on this thing? Is there a better solution than just swiping around while playing?".
Obviously the answer is: "Yes, with [*another expensive gadget that is already on the market*](https://www.thomann.de/it/airturn.html)". Being cheap as I am (the iPad is a reconditioned one, and still really too expensive for me), I decided to try design one, using an ESP32, a lipo battery charger circuit and a couple other components. This is the result (up until now), hope you like it!

## Parts needed:
* ESP32 board, I used a ESP-WROOM-32 after removing all the header pins, to have a shorter board. Going back I would have used a board with an integrated charging circuit, like a [Lolin32](https://it.aliexpress.com/item/33006577783.html?spm=a2g0o.productlist.0.0.7ccb58a6xTtykC&algo_pvid=e232b403-1504-4679-a534-d3c7af5d4a1a&algo_exp_id=e
