This is my first PCB, or you can also say my first ever hardware project that I ever made. In the beginning, I was scared to make it because it was so complex, but after some time It started to get fun. But that does not mean it got easier; it was still complex and gave me a headache. I never thought that I would be able to make a PCB as my first hardware project.
Features:
The following is a list of some features below:
- Glow-in-the-dark: whenever you take it into the darkness, the LEDs turn on, and its eyes start glowing, but in the light, the LEDs turn off.
- You can put it in your room as a decoration so at night when you turn off the lights, it will turn on and look beautiful.
- You can also attach it to your keychain, a great gift for a tech guy.
Inspiration:
This PCB is highly inspired by a robot named Roz from the movie "The Wild Robot." I took a beautiful scene from the movie where the robot is holding a little duck and converted that into a PCB

Questions
How big is the Ari First PCB PCB?
It measures 75.7 × 66.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ari First PCB use?
10 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Ari First PCB KiCad files?
From the aridev24/Roz-PCB repository on GitHub, at the commit this page was made from: the board is Ari-First-PCB/Ari-First-PCB.kicad_pcb and its schematic Ari-First-PCB/Ari-First-PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ari First PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask aridev24 before reusing the design.
