8x8 Audio Spectrum Level LED Indicator Board FFT 8x8 Acoustical Spectrum LED Light Audio Indicator DIY Kit for Arduino

4. Identify components in this kit.
1>. Resistance.(NOTE the first two number is mark on resistance.The third is value of resistance)
1). Resistance 3303=334=330K ohm
2). Resistance 100=10=10 ohm
3). Resistance 33=33=33 ohm
4). Resistance 1001=102=1K ohm
2>. Capacitance.
1). 10uf Capacitance: 106, transparent plastic packaging.
2). 0.1uf Capacitance: 104, white hard paper packaging.
3). If user has take out these capacitance and can not identify them. User can identity them by thickness. The more thick is 10uf, the other is 0.1uf.
3>. LED.
1). User can identify negative pole and positive pole of LED as following picture:
NOTE: Sometime LED will different as picture above.  Some LED has two green dots on positive or a triangle-shape on reverse side. The identify way is the same.
2). If your kits have four different  color  of  LED,  The  color  can be detection by digital multimeter or  3.0V  battery.  (If  you  test LED  by  3V  battery,  please  be  carefully.  3V  battery  can  not  conne ct to LED for a long  time,  our  method  is  just  for  test.  Otherwise  LED will be damaged.)
3. Component listing
3). H Mode: high sensitivity mode. It will display “H” on LED screen. In this mode, It can filter the weaker jamming signal, It is sensitive to the interference of power supply.
2). M Mode: medium sensitivity mode. It will display “M” on LED screen. In this mode, It can filter the weaker jamming signal, Signal detection sensitivity.
1). L Mode: low sensitivity mode. It will display “L” on LED screen. In this mode, It can filter weak jamming signal, It is not sensitive to the interference of power supply.
It will change signal detection sensitivity by long press one time button(more than 1.5 seconds).
3>. Sensitivity Mode. ( press the button more than 1.5 seconds)
3). F Mode: fast flash. It will display “F” on LED screen. In this mode, It's the fastest display and update.
2). S2 Mode: slow flash 2. It will display “S2” on LED screen. In this mode, Its speed is appropriate.
1). S1 Mode: slow flash 1. It will display “S1” on LED screen. In this mode, It's the slowest display and update.
It will change a display mode by short press one time button(less than 1.5 seconds).
2>. Change Display Mode. ( press the button less than 1.5 seconds)
Press button before power on, then power on, IC will enter into test mode automatically. In this mode, it can test led and circuit.
1>. Test Mode.
Function Menu selection by a button. It has three different operations as following:
2. Function declaration.
9>. There are three Sensitivity mode can be selected(High,Medium,Low).To adapt to the different power supply environment.
8>. There are three display mode can be selected(Fast flash, Slow flash 1,Slow flash 2).Provide the feeling of cool.
7>. Professional audio decoding. It can display equency and amplitude for audio signal.
6>. It design for audio equipment. Being used in all kinds of audio output device widely.
5>. We have programmed the code to FFT2088.It can supply 8*8 LED.
4>. It is no need for filter circuit. It can driver dot matrix, spectrum indicating and so on.
3>. There are four fixed mounting holes on PCB.
2>. Circuit design is simple. Add current limiting resistor drive LEDs directly.
1>.Audio automatic gain control. Always show the best visual effect.
