APR9600 VOICE MODULE PDF
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.

Gener- ally, we put power traces on the top of the board, jump- ing only to the bottom if a part cannot be soldered arp9600 the top plane like a relayand vice- versa.
This information is provided by the GPS with the help of the data it receives from the satellites. When using a double sided board we must apr9600 which traces should be on what vioce of the board.
When the satellite signal is receieved by the GPS, the latitude and longitude of the current location is displayed on the LCD. 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.
APR Voice Recording Playback Module Support Single Chip $ Free Shipping @
After getting the signal, if we want to store the present location as an alerting location for vokce blind person, the following procedure will do the needful — i. The recordable sound is changed to voice signal using microphone and given to IC 1 through differential amplifier.
The module comes with a GPIO control pin for controlling the power. For this, we have to switch ON the voice module by connecting the power supply batte- ries.
The microcontroller is programmed in such a way that depending on the satellite information of location the predefined location name will be announced. Connect a appropriate speaker should not lower than 8 Ohms at LS1, For playing a recorded message you just need to press and release any of the switch available in that particular mode once.
This is due to the fact that the PIC has no stack to push variables onto, and also because nodule the way the compilers optimize the code.

All the pins of the ports are for interfacing input output devices. Void data means if voiice GPS Receiver is unable to get the satellite signal it will give the previous data which may not be current location value. Recorded sound is retained ar9600 after power supply is removed from the module. Easy Electronic Projects 5. Another PiP would sound to denote the end of recording.
All normal C data types are supported along with pointers to constant arrays, fixed point decimal, and arrays of bits.
60 seconds Voice Record – Playback module
The working of the system can be divided into two phases. Here is projects called Voice recording and play back using chip APR When making a PCB we have the option of making a single sided board, or a double sided board. Switches marked M1 to M8 are available in this mode. Check on this website http: When we finish recording, the selection button is released.

The term is most commonly applied to electrical voicr supplies, less often to mechanical ones, and rarely to others. Proteus is a software which accepts only hex files. To achieve this mode J1 and J2 should be closed. The IC can operate in one of two modes: Release the restart button after 1sec iv. I edit and author this site. Also select the source for recording through CN1 Connector.
By this it can trace out the modile from the destination and pro- duce an alarm to alert the user in advance. GPS based blind man device with user input interfacing voice based intellectually finds the current location and gives the alert to the blind man if it was his destination area.
It consists of 8 pins from B0 to B7 Port C: Then, using a push button and different selection buttons we record the voice. Project Using and 4.
