🌀 What Is It?
🧠 How the Idea Was Born
🧰 What I Used
Arduino Uno
Adafruit Audio FX Sound Board
Ping pong balls + LEDs for the disco vibes
Bearings, wood sticks, wires, and lots of cardboard
A dash of ✂️ cutting, 🔩 fixing, and 🎨 decorating
🔧 How I Made It
Step 1: Make the Roller
Cut cardboard circles and used bearings to make smooth-spinning reels.
Step 2: Manu Stickers
Collected free food icons and arranged them into neat sticker layouts using Illustrator, then printed and wrapped them around each roller.
Step 3: Rotating Structure
Constructed a sturdy (and slightly wobbly) box from cardboard, with slots to hold the rollers in place.
Step 4: Arduino and Code
Wired up the Arduino, LEDs, and sound board so that every spin lights up and plays a dramatic ta-da! sound.
Step 5: Final Flair
Added hand-drawn doodles, LED ping pong bulbs, and a big red spin button—because every decision machine needs a dramatic button.
