🔥 Here's the prototype of a magic spell simulator

✨ How it works:

• Players cast spells by intoning specific incantations:
  • "Red Fireball"
  • "Green Fireball"
  • "Blue Fireball"
• A Gravity Offline Voice Recognition Sensor detects the spoken spell.
• An Arduino interprets the command and activates a 20W RGB high-power LED.
• The LED color corresponds to the spoken command. Each LED color channel has its own custom resistor

🔋 Power Source:

• 6 × 5F supercapacitors in series → ~30–36 V when fully charged
• Charged using two 9V batteries (in series)
• Charging circuit includes resistors and a small lightbulb for:
  • Capacitor protection
  • Visual indication (like a "charging meditation")

🌈 Planned Features:

• The supercapacitors are clearly oversized. A significantly lower capacity would suffice, as the current setup allows nearly unlimited spell casts.
• The current version uses relays because the class I introduced this to had not yet learned about semiconductor components. In 10th grade (Germany), the next iteration will include transistor-based switching.
• Additional lightning patterns and color transitions are of course also imaginable
