VOICE RECORDER AND PLAY BACK MODULE(ISD 1700)

VOICE RECORDER AND PLAYBACK MODULE

Voice recorder and playback module is a made for the purpose of recording those messages and playback which required frequently at some places like platform, train, instruction, mobile, etc. When I started to work on this project I was not able to find some easy instruction to made one for me. So I decided to put it on my blogs so that other can made this one easily.

Now a my voice recorder module is based on IC ISD17XX/1720 which is DIP package and 2.4-5 volt operating voltage. It is a multi-message voice record. It can be operated standalone or by microcontroller(SPI) mode. Recording are stored into on-chip flash memory, providing zero power message storage.

In the spi mode , the user has full control via serial interface to operate the device Now here is the pin diagram of the ISD1700

ISD1700 pin description:
PINDESCRIPTION

Modes of operation –There are two modes of operation Standalone (push button control) and microcontroller (SPI) mode.

·         Standalone (push button) mode-

          We can use this mode by REC,PLAY, FWD, Erase, VOL, RESET. To control desired operation.                       After completion of operation its automatically goes into power down mode.

·               SPI mode
           In SPI mode control of the device is achieved by 4 wire serial interface via SPI commands.

NOTE:- FOR MORE DETAIL PLEASE LOOK THE DATA SHEET OF THIS IC.  CLICK HEAR

Now the circuit:

  6. Hi,
    I followed this tutorial. And when I connect the batteries, the voltage drops too as low as 0.50 volts instantly. the batteries as such show me 9V. l7805 gives a stable 5V. but the moment I connect to breadboard, the voltage drops. Can you guide on this ?
