Flashing circuits Led by music (in digital)
You hear a lively music and feel as though something is still missing, so why not do a flashing LED circuit to the beat to mix with you into the world of melody. I will teach a simple way to do that.
Product after completion
Principle diagram
The operating principle is simple: the audio signal from audio source was taken to the pole B of the transistor size for the transistor level to lead LED. Audio signal may be weak when the transistor power line strength to create different looks such as LED flashes to the beat.Depending on the power supply voltage for the circuit that you need to figure out whether to add or limit line. The circuit used in the power source and audio from ipod 9VDC.Signal Input 1 and input 2 is taken from the 3 cups jack audio source connected as shown below, you cut a head of the jack 3 cup will see three wires, including red and white wires that will connect the audio signal into 2 Input, GND wires are connected to the rest mass
Attach the three wires to the circuit
Upon completion, you can leave the box and decorate your liking.
Skip the box for any neat!
This is just a very simple circuit, you can use to implement the idea VDK, plus RGB LED can be used for more vibrant colors.
