Kitty ears with bluetooth remote

thanks to Oleg T 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

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.
