🎃 Project Description

This project is a collection of Halloween-themed interactive PCB badges, each designed with colorful silkscreen and creative electronic effects for the OSHWLab Halloween Contest.

1. 💀 Skull Memory Badge ( tested under breadboard only )
   A skull-shaped badge with two addressable RGB LEDs that change color when pressing a button (mounted on the back to preserve the artwork).
   It includes a mini-game: one color is shown first — you must remember it. Then, several colors flash rapidly, and when your color appears, you must press the button as fast as possible!
   A small vibration motor provides haptic feedback when pressing the button or when the game reacts. Powered by a flat coin cell, with a keychain hole for easy attachment.

2. 🎃 Pumpkin “Candle” Badge  ( tested under breadboard only )
   A pumpkin face with flickering LEDs that simulate a candle effect for the eyes and mouth — simple, elegant, and perfect for Halloween night.

3. ☠️ Reaper Keychain ( done )
   A reaper-shaped PCB keychain with a fluorescent liquid-painted scythe, giving a glowing effect under UV light.

4. 📞 Scary Movie “Wazzup” Badge  ( under test ) 
   A talking badge inspired by the Scary Movie ghost mask. It has RGB eyes, an MP3 player, a distance sensor, and capacitive touch sensors.
   When someone gets too close or touches it, the badge plays spooky sounds!

5. 🧟 Zombie Mystery weapon box (Call of Duty BO2)  ( in the future ) 
   A keychain badge that plays the bonus and the mystery box sound effects inspired by Call of Duty: Black Ops II.

6. 🧟 Zombie Keychain (Call of Duty BO2)  ( in the future ) 
   A small keychain badge that plays zombie sound effects inspired by Call of Duty: Black Ops II.

7. ⚗️ Cauldron Badge (Repo Game) ( in the future ) 
   A cauldron-shaped keychain that reacts to shaking by producing sounds and vibrations, along with glowing RGB LED effects that simulate bubbling potion light.

8. 🕸️ RGB Spider Web Badge (ESP32)  ( in the future ) 
   A larger badge with a spider-web shape, featuring programmable RGB LEDs controlled by an ESP32.
   It includes an online interface for programming light patterns and reacts to ambient sound, creating a synchronized “party” effect.

All these designs are part of the EasyEDA Halloween Contest – Colorful Silkscreen Magic 🎨.
Some PCBs may not be fully produced before the deadline due to time constraints, but all concepts are open-source and designed in EasyEDA Pro.
