Description

"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.

The PCB

Gioia's PCBs are made by PCBway https://pcbway.com/g/kY6w10

I chose this supplier because the quality of the PCB and the assembly of the components is of great quality. The assistance is excellent and the delivery times are always respected

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

Versions

The project is available in 2 versions:

21 monochrome leds:

All the documentation to make it is available here: https://github.com/Green-bms/gioia/tree/master/21%20monochrome%20leds%20version

8 RGB leds:

Each LED can light up in one of these 7 colors: red, green, blue, yellow, fuchsia, aqua, white.
All the documentation to make it is available here: https://github.com/Green-bms/gioia/tree/master/8%20RGB%20leds%20version

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.

Open source Development applications

The project was created using the following Open source applications:

• KiCad : to design pcb
• Arduino IDE : to design the code for Attiny85 microcontroller of device animations
