2. AIM-
• Abstract-The article proposes a design scheme 01' LED light music rhythm based on
virtual instrument, studying the audio signal collection, processing and application.
Instead of a general.data collection card, using computer sound card as hard
ware.acquisition audio signal and transmit It to the computer. On the LathEw software
platform, based on signal processing function, audio playback and signal processing
system is designed, which anlasis and process the audio signal at different frequencies of
Input signal strength to generate the output signal associated with the frequency and
intensity of thc input audio signal, so that realizes the LabVlEW virtual LED matrix in the
program and the actual LED matrix mxI-time synchronously to nicker with the rhythm of
the music. The design of the audio signal acquisition and precessis system 15 provided
with good inner machine Interface, strongreal-time performance and convenient
operation. It can be extended Its function according to the needs of user. With
boardapplicaution prospect, It can be applied to a variety ofandio W collection and
processing Iields such as speech recognm“, environmental noise monitoring. etc.

5. WORKING PRINCIPLE-
• It works on the principle of charging and discharging of
Qpacitors C1 and C2. Current from the positive of battery flows
through first set of LEDs Dl-D3 resistor R1. Resistor R1 limits
current through the LEDs to protect them. The current through
R1 charges capacitor C2. It then discharges through the base of
T2 and resistor R4. This gives base current to T2 and it
conducts. As a result second set of LEDs D4D6 lights as the
current flows through ***********In the schematic the are of
Well the working principle is simple when the
microphone catches any sound of high base the
transistor gets grounded making the circuit

8. ADVANTAGES -
-Energy efficient – LED’s are now capable of outputting 135
lumens/watt
Long Lifetime – 50,000 hours or more if properly engineered
Rugged – LED’s are also called “Solid State Lighting (SSL) as they
are made of solid material with no filament or tube or bulb to break
No warm-up period – LED’s light instantly – in nanoseconds
Not affected by cold temperatures – LED’s “like” low temperatures
and will startup even in subzero weather
Directional – With LED’s you can direct the light where you want it,
thus no light is wasted
Excellent Color Rendering – LED’s do not wash out colors like other
light sources such as fluorescents, making them perfect for displays
and retail applications
Environmentally friendly – LED’s contain no mercury or other
hazardous substances
Controllable – LED’s can be controlled for brightness and color

9. DISADVANTAGES-
• 1 .High initial price
• 2.Temperoture dependonce
• 3.Use 'In Winter conditions
• 4.!mpoct on insects

10. FUTURE SCOPES-
• Cell phone background lights for Rythemic flashing according to the
• Ringtone or incoming call alert.
• In disco and party lounges
• In music player and amplifiers.
• Simple sound-to-light unit for music .
• Sound inductor.
• For the hearing impaired:can be used to indicate the telephone.
• Door bell.
• In musical fountains.

11. CONCLUTION-
• This article proposes a scheme of LED music rhythm lamp design
based on virtual insu'umcnts. and studies the collection. processing
and application of audio signals. A computer sound catd is used as
the hardware to collect the audio signal instead of the nonnal data
acquisiticm card and transmitted to the computer. Based on (ht:
signal processing function. the audio file p‘ayback and signed
processing system is designed on the LabVIlEW software r-Iatfonn,
and the: input audio signal is d'widcd into dit‘t‘crcr. frcquctwy bands
for signal strength. The analysvs and processing to generate the
output signal related to the frequency and intensity of 13%;input
audio signal enables the Virtual LED matrix and the actual LED matrix
in the LabVIEW program to blink in synchron with the. rllylhm of line
music .
