Upgrading a Mini Slot Machine with Microcontroller & LCD!
I decided to take a mini keychain slot machine and give it a modern tech twist! The original mechanical design lacked excitement - its reels spun simultaneously, with no real sense of winning. So, I decided to hack it with a XIAO RA4M1 microcontroller, swap the reels for an LCD display, and add sound effects for a more immersive experience!

In this video, you'll see
How I disassembled the keychain slot machine
The components used and challenges I faced
Step-by-step circuit building & coding with Arduino
The final assembly & showcase of the hacked slot machine
