README
README.mdPathfinder!
This is my project, the Pathfinder. It has three MX-style switches and three LEDs of red, green, and blue colours respectively. It also includes one RGB LED. The firware is coded such that -
-
Press Button 1 → Blue LED ON, RGB shows blue
-
Press Button 2 within 2 seconds of Button 1 → Green LED ON, RGB shows green
-
Press Button 1 AND Button 2 within 2 seconds of each other → Blue + Green LEDs ON, RGB shows cyan (blue + green)
-
Hold Button 3 → Red LED ON, RGB shows red
-
Combine Button 3 + Button 1 → Red + Blue LEDs ON, RGB shows magenta (red + blue)
-
Combine Button 3 + Button 2 → Red + Green LEDs ON, RGB shows yellow (red + green)
-
Press all three buttons together (B1 + B2 + B3) → All LEDs OFF, RGB shows rainbow animation 🌈

Questions
How big is the Pathfinder PCB?
It measures 60.4 × 39.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pathfinder use?
16 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 Pathfinder KiCad files?
From the SabhyaAggarwal/Pathfinder repository on GitHub, at the commit this page was made from: the board is PCB/Pathfinder.kicad_pcb and its schematic PCB/Pathfinder.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pathfinder design in my own project?
Its repository states no licence, so its author keeps all rights: ask SabhyaAggarwal before reusing the design.
