Introduction: Flashing Leds With Music
This is a simple project. We have a bunch of leds that flicker with changing intensity of sound.
What we need are
1 a power supply 5v
2 LM339 ic (comparators)
3 leds 4 (any colour)
4 resistors 1k (13pieces), 1M(1piece), 10k(1)
5 capacitor 0.1(1)
6 sound sensor module compatible with Arduino
7 jumper wires
9 and the circuit diagram!
Step 1: Assembling the Parts. According to the Diagram
It's just one step. Assemble the circuit parts as describes in the diagram and you are good to go. You just need to adjust the potentiometer on the sensor! That's all.
