Kitty ears with bluetooth remote

thanks to [Oleg T](https://www.thingiverse.com/Topdevice/about) for the original design.

Arduino sketch for the band is inspired by : https://www.chipdip.ru/product/kitty-ears

To understand how to connect 2 arduino by Bluetooth go to fantastic [Martyn Currey website](http://www.martyncurrey.com/connecting-2-arduinos-by-bluetooth-using-a-hc-05-and-a-hc-06-pair-bind-and-link/)

BOM:
- 2 arduino pro mini or other little arduino (the nano v3 is too big)
- 2 HC-05
- 2 1k resistor
- 2 2.2k resistor
- 2 SS12F15-G5 switch
- 2 9v connector
- 4 micro servo 9g
- 1 L7805 (may be optionnal ? you can try to connect directly the servos and hc-05 to arduino but i'am not sure because on the spec of the pro-mini it's 150mA max when raw powered)
- a little girl for the tests

Space is reduced to the minimum for electronics, use rather short threads.
