Introduction: 4 Music Reactive LEDs Circuits|| MIC/AUX Cable/Speaker
This is a circuit which reacts to ambiance music and glows the LEDs with the beats of the music.
Here, I will show you four different ways to make a Music Reactive LEDs Circuit using :-
1. Single Transistor
2. Two Transistors
3. AUX Cable
4. Speaker
Step 1: Materials Required
These are the Components Required for making the circuit:
1. Using Single Transistor
• Condenser Microphone
• Transistors: BC 547
• Resistors: 47 K Ω, 330 Ω
• LED
2. Using Two Transistors
• Condenser Microphone
• Transistors: BC 547 (2)
• Resistors: 1M, 10K (2)
• Capacitor: 0.1 μF (100nF)
• LEDs (2)
3. Using AUX Cable
• Old Earphones (For AUX Cable)
• Transistors: BC 547 (2)
• Resistors: 1M, 10K (2)
• Capacitor: 0.1 μF (100nF)
• LEDs (2)
4. Using Speaker
