The main concept of operating this software
and hardware is based on “monotonic audio signals converting into clock pulses“. User can
operate a device
with monotonic audio signals from phone or any other device which can
generate monotonic audio signals. By using this software user
can program the
pulses.
TECHNOLOGIES USED:
- JAVA Standard Edition : Version:7.0
- JAVA Micro Edition (J2ME)
- HTML (Hyper Text Markup Language)
- JAVA SCRIPT
TOOLS USED:
- JAVA NET BEENS
- WIRELESS
TOOLKIT 2.5.2
SOFTWARES REQUIRED:
1.
JAVA
STANDARD EDITION (VERSION
2.0/3.0/4.0/5.0/6.0/7.0)
2.
WIRELESS
TOOLKIT 2.5.
HARDWARE REQUIRED:
1.
J2ME compatible phone : It is for produce programmable
sound signal.
2.
555 TIMER :
Here 555 timer used for the producing one second delay. After one
second it enables
the latch to give input to register
from counter
3.
The Amplifier and
converter (monotonic audio signals
into clock pulses) amplifies
the sound signal.
4.
Counter :
Counter will increments
its values by
clock pulses given
by clock generator.
5.
Latch : It
is used as
gate for enabling
and disabling data
transfer
WORKING:
1.
The
software loaded in
phone produces sound
signals.
2.
The
sound signals are
converted into clock pulses
by using amplifier.
3.
Counter increments its value by clock pulses
given by amplifier.
4.
The
same clock pulses
resets the 555
timer.
5.
If
the delay produced
by 555 timer reaches
1 second then it allows the latch to
enter data into
register then resets
the counter.

LED sequencer: follows the rhythm of music or speech, 9V
Battery-operated portable unit
The basic circuit illuminates up to ten LEDs in sequence, following the rhythm of music or speech picked-up by a small microphone. The expanded version can drive up to ten strips, formed by up to five LEDs each, at 9V supply. IC1A amplifies about 100 times the audio signal picked-up by the microphone and drives IC1B acting as peak-voltage detector. Its output peaks are synchronous with the peaks of the input signal and clock IC2, a ring decade counter capable of driving up to ten LEDs in sequence.
An additional circuit allows the driving of up to ten strips, made up by five LEDs each (max.), at 9V supply. It is formed by a 10mA constant current source (Q1 & Q2) common to all LED strips and by a switching transistor (Q3), driving a strip obtained from 2 to 5 series-connected LEDs. Therefore one transistor and its Base resistor are required to drive each of the strips used.

Notes:
- The sensitivity of the circuit can be varied
changing R4 value.
- C4 value can be varied from 220 to 470nF in
order to change the circuit speed-response to music peaks.
- Adopting the additional circuit, only one
item for R10, R11, Q1 and Q2 is required to drive up to ten LED strips. On
the contrary, one item of R9 and Q3 is necessary to drive each of the
strips you decided to use.
- Each R9 input must be connected to IC2 output
pins, in place of the LEDs D2-D11 shown. R8 must also be omitted.
- Whishing to use a lower number of LEDs or LED
strips, pin #15 of IC2 must be disconnected from ground and connected to
the first unused output pin.
- For example: if you decided to use 5 LEDs,
pin #15 of IC2 must be connected to pin #1; if you decided to use 8 LEDs,
pin #15 of IC2 must be connected to pin #9 etc.
- Current drawing of the circuit is about 10mA.
- Whishing to use a wall-plug adapter instead of a 9V battery, you can supply the circuit at 12V, allowing the use of up to 6 LEDs per strip, or at 15V, allowing the use of up to 7 LEDs per strip.
