DIY Kit FFT 8x8 Audio Indicator Yellow FFT Voice Frequency Control LED Precise
DIY Kit FFT 8x8 Audio Indicator Yellow FFT Voice Frequency Voice Control LED Precise
1. Introduce.
1>. Working voltage: 5V.
2>. PCB size: 75*45mm.
3>. There are four fixed mounting holes on PCB.
4>. It is no need for filter circuit. It can driver dot matrix, spectrum indicating and so on.
5>. We have programmed the code to FFT2088.It can supply 8*8 LED.
6>. It design for audio equipment. Being used in all kinds of audio output device widely.
7>. Professional audio decoding. It can display equency and amplitude for audio signal.
8>. There are three display mode can be selected(Fast flash, Slow flash 1,Slow flash 2).Provide the feeling of cool.
9>. There are three Sensitivity mode can be selected(High,Medium,Low).To adapt to the different power supply environment.
10>. Audio automatic gain control. Always show the best visual effect.
11>. Circuit design is simple. Add current limiting resistor drive LEDs directly.
2. Function declaration.
Function Menu selection by a button. It has three different operations as following:
1>. Test Mode.
Press button before power on, then power on, IC will enter into test mode automatically. In this mode, it can test led and circuit.
2>. Change Display Mode. ( press the button less than 1.5 seconds)
It will change a display mode by short press one time button(less than 1.5 seconds).
1). S1 Mode: slow flash 1. It will display “S1” on LED screen. In this mode, It's the slowest display and update.
2). S2 Mode: slow flash 2. It will display “S2” on LED screen. In this mode, Its speed is appropriate.
3). F Mode: fast flash. It will display “F” on LED screen. In this mode, It's the fastest display and update.
3>. Sensitivity Mode. ( press the button more than 1.5 seconds)
It will change signal detection sensitivity by long press one time button(more than 1.5 seconds).
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.
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.
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.
3. Component listing.
NOTE: This kit has 64pcs LEDs, you can weld LED on any solder joints from D1 to D64, and you had better make one row or one column by the same LED
