Upgrading a Mini Slot Machine with an LCD & Microcontroller

I decided to take a mini keychain slot machine and give it a modern twist! In this project, I replaced the original mechanical internals with an LCD screen and a microcontroller, transforming it into a tech-enhanced version of itself. In this video, I’ll walk you through the process of modifying the slot machine, including the components used, the challenges faced, and the final result. Whether you're into electronics, retro gadgets, or just enjoy creative mods, this is one you won’t want to miss!
