Parallel Circuit Mastery: LED & Buzzer Together | DojoLab Activity 03 | Electronics Projects

⚡ *Activity 03: Parallel Circuit - Combine LED Light & Buzzer Sound!*

Master parallel circuits by combining both light AND sound in one smart project.

📦 *Components Used:*
• LED + 220Ω Resistor
• Piezo Buzzer
• Push Button Switch
• 3x AA Battery Holder
• Breadboard & Jumper Wires

🎯 *What You'll Learn:*
1. Parallel vs. Series circuits (Key difference!)
2. Multiple components, single power source
3. Independent control in parallel paths
4. Current division in parallel circuits
5. Building complex systems from simple parts

🔬 *Science Behind It:* In parallel circuits, each component gets FULL voltage, but current splits between paths. This is how homes are wired!
