README
README.mdAutonomous Vending Machine
A vending machine built from scratch — custom PCB, Arduino firmware, and a dedicated UI screen. This repo has everything from the KiCad design files to the embedded code running on the hardware.
Project Structure
- /Hardware — KiCad schematics, PCB layout, and 3D renders
- /Firmware — Arduino Nano code handling motor control and dispensing logic
- /Software — Screen & UI documentation
- /Media — Photos and demo videos
What's inside
The PCB was designed in KiCad to handle power distribution and sensor wiring cleanly. Dispensing is handled by logic-controlled motors, and there's a small screen for user interaction and feedback. Components were chosen to keep the build cost reasonable without cutting corners on reliability.

Questions
How big is the Vendingmachine PCB?
It measures 105 × 104.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Vendingmachine use?
15 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 Vendingmachine KiCad files?
From the MohsinbinAlthaf/Custom-Vending-machine repository on GitHub, at the commit this page was made from: the board is Hardware Pcb/vendingmachine.kicad_pcb and its schematic Hardware Pcb/vendingmachine.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Vendingmachine design in my own project?
Its repository states no licence, so its author keeps all rights: ask MohsinbinAlthaf before reusing the design.
