Presented device is used to display notifications from mobile phones - FB, Messenger, WhatsApp, Instagram. The assumption is to support devices equipped with the IOS operating system.
The device is based on the Arduino Nano microcontroller. The connection between the device and the phone is based on bluetooth.
Notifications are displayed on the OLED display placed under a dark blend and with the help of a soft ambient backlight at the base of the device - it gently illuminates the desk surface so as not to affect the workflow.
Ambient lighting in any color obtained thanks to the Adafriut Neopixel 24-led ring.
The device contains the AT-09 / HM-10 bluetooth module supporting the BLE standard enabling continuous communication.

Extras:
The design can be used as a housing for any sensor, i. e. temperature, humidity, etc. Feel free to modify the range of operation and additions in the device.

Software:
It must be created, components are selected in a way that allows implementation of the solution. To create a program you should use libraries:

• ANCS https://github.com/robotastic/ANCS-Library
• HM-10 https://github.com/cyborgsimon/HM_10_Serial_Port_BLE
• Neopixel Ring https://github.com/adafruit/Adafruit_NeoPixel
• OLED display https://github.com/adafruit/Adafruit_SSD1306
  The software at this moment has been postponed in time when it comes to creation.

BOM:

• 5g transparent material
• 140g your favourit material (ABS, PLA, PET etc.)
• Plexi 3mm (smoked/dark transparent, diameter 66,5mm )
• Arduino Nano V3;
• Adafruit NeoPixel Ring - 24 x 5050 RGB LED with Integrated Drivers
• Bluetooth module AT-09/HM-10
• 0.96 inch OLED I2C display
• Mini USB cable + 5V PS ( i.e. phone charger)
• Wires

Dimensions : 80x80x32 mm (without powercord)
