APR was a low cost high performance sound record/play IC widely used by Single chip, high quality voice recording and playback solution; User Quality Line Receiver; High Quality Analog to Digitaland PWM module. Voice Module 60 Sec project will playback and record up to 60 seconds of voice message. This circuit is an This circuit is based on APR IC from Aplus. General Description. The APR devi ce offers true single-chip voice recording, non-volatile storage, and playback capability for 40 to 60 sec- onds.

Pin 1 is MCLR master clear pin pin also referred as reset pin. This device is designed to provide a voice based an- nouncement for the user, i. The locations names are pre recorded in the voice circuit and are announced when the person reaches those particular locations. Electronic Game and Fun Projects. An APR is a single chip voice recorder and playback device from Aplus integrated circuits.
Now when the blind person enters these regions loca- tions with this system the voice module will announce the location names as we had recorded them with respect to the stored locations. Voice Module 60 Sec project will playback and record up to 60 seconds of voice message.
The program which is to be dumped into the microcon- troller is edited, compiled and executed. To- tal sound recording time can be varied from 32 seconds to 60 seconds by changing the value of moule single resistor. Can you help me? PIC16F is a 40 pin microcontroller. My requirement is to record four different sound in one circuit and play any one sound when i want. The module comes with a A;r9600 control pin for controlling the power. These compilers are specifically designed to meet the unique needs of the PIC microcontroller.
This project would be a great fit for your railway model. After storing the location swe need to restart the system. It consists of 6 pins from A0 to A5 Port B: Void data means if the GPS Receiver is unable to get the satellite signal it will give the previous data which may not be current location value. According to the datasheet, if you press and hold the message button M1-M8 the message is replayed repeatedly. Recorded sound is retained even after power supply is removed from the module.
To achieve this mode J1 and J2 should be closed. In this system, the GPS receiver and the control buttons are the input modules to the microcontroller while the Voice module and the LED indicators are the output modules to the microcontroller. PIC compiler is a software in which the machine lan- guage code is written and compiled. If a lot of parts are being used in a small space it may be difficult to make a single sided board without jumpering over traces with a cable.
The procedure is the same as described above in MOD8, and the keys available in this mode are M1 to M4.
APR9600 Voice Recording Playback Module Support Single Chip
It should be noted that if a trace is running on the top layer, check with the components to make sure you can get to its pins with a soldering iron. The first phase would involve recording of the voice in the voice module. Learn how your comment data is processed. Pin 13, 14 are used for connecting the crystal oscillator to generate a frequency of about 20MHz. This project can be extended by incorporating a GSM module.
There are basically four families of PIC microcontrollers: Active data means, when the GPS receiver gets the satellite sig- nal it will give the current location values. This software is used for designing the circuit.

The replayed sound exhibits high quality with a low noise level. Recording will end when you release both these keys and when it reaches the end of the segment.
In serial access mode, sound can be recorded in sections. The IC can operate in one of two modes: Switches marked M1 to M8 are available in this mode.
The above disadvan- tage can be removed by using a higher efficiency GPS receiver. To record a message in any on of this location, you need to keep the Record Switch SW10 pressed with mofule finger and the Segment Switch pressed.
Gener- ally, we put power traces on the top of the board, jump- ing only omdule the bottom if a part cannot be soldered onto the top plane like a relayand vice- versa. This paper describes the concept using a microcontroller based system.
While both the buttons are pressed, we hear a beep sound from the speaker, indicating that we can release the push but- ton.
This circuit will help you record and zpr9600 a 60 seconds voice message stored on it. It stores the data of the current location which it receives from the GPS system, so that voicr can make use of the data stored to compare with the destination location of the user. After getting the signal, if we want to store the present location as an alerting location for the blind person, the following procedure will do the needful — i.
