Electronic wearable device

"Gioia" in Italian means joy.

I wanted to call this project this way in the hope that it will bring joy and happiness to those who wear it.

This gadget of 3 cm of diametrer can contain a maximum of 24 single-color LEDs or 8 RGB LEDs.

The infinite animations, which also include letters and symbols, are managed by an Attiny85 microcontroller.

In this version Each LED can light up in one of these 7 colors: red, green, blue, yellow, fuchsia, aqua, white.

Battery

The device is powered by a 30mAh LIR1632 rechargeable lithium battery.

Charging is done via a micro USB connector and takes about 90 minutes from 0% to 100% The device lasts for about 5 continuous hours

Microcontroller

The device's LEDs are driven by an Attiny85 microcontroller and 3 74HC595 shift registers.

The LED animations that can compose various light games, texts and symbols, are programmed in the code to be loaded into the microcontroller

Programming the microcontroller is very simple: you need to power the device via USB and connect the 4 pins of the ISP programmer to the pads shown in the pictures below.
