Photobone Ring

LED Ring project to be used together with Photobone Studio.

The firmware is using the V-USB library under the GPL v2 license. This project itself is also published under the GPL v2 license. Also, you gotta download Fastled in the arduino library manager.

Required components

• 2 ATTINY85 arduinos: one controlling ring, one communicating through USB with PC

  • The arduinos are connected as described in the Pinout section

• WS2812 (not WS2812B - you might need to change some code for that) 24-LED ring (different LED count theoretically possible when adjusting source code)

Status indication

• Violet: booting/waiting for arduinos to communicate
• Red: not connected with Photobone Studio

Pinout

• ARD_RING - Arduino controlling the ring
• ARD_USB - Arduino controlling the usb
• USB_PORT - connection with the USB port (no need to wire anything, is done on the board itself)
• LED_RING - The LED ring itself
