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.

It is also possible to control the IC using external digital circuitry such as micro- controllers and computers. A Pip sound will play through the speaker to denote recording start. Please refer to http: I edit and author this site.

Leave a Reply Cancel reply. This project can be extended by incorporating a GSM module. Release the restart button after 1sec iv. The project provides four different modes of voice message to be recorded and played, viz i MOD8: It consists of 8 pins from D0 to D7 Port E: PIC16F is a 40 pin microcontroller.

Active data means, when the GPS receiver gets the satellite sig- nal it will give the current location values. Currently they are some of the most popular microcontrollers, selling over million devices each year. Jumper J3 on the PCB to select audio source.

Voice Recording and Play Back Circuit using APR9600

Here instead of an alarm sound the blind man can directly hear the location rec- orded by the user itself. Once the ic starts playing will it be playing again and again itself or it will stop after playing the recorded music 60 sec. Entire 60 segment is available in a single shot mode. While both the buttons are pressed, we hear a beep sound from the speaker, indicating that we can release the push but- ton.

It consists of 6 pins from A0 to A5 Port B: In order to hear what we have recorded, we just need to press and hold the corresponding selection button for 1sec and the recorded message would be replayed.

Recording will end when you release mkdule these keys and when it reaches the end of the segment. Pin 1 is MCLR master clear pin pin also referred as reset pin.

It stores the data of the current location which it receives from the GPS system, so that it can make use of the data stored to compare with the destination location of the user. Complete Electrical Symbol 3.


How can i help you? Mpdule pls reply to my question Once the ic starts playing will it be playing again and again itself or it will stop after playing the recorded music 60 sec If I want to play it without stoping how should I do it 2 years ago. The procedures is the same as described above in MOD8, and the keys available in this mode modlue M1 and M2. Microcontroller is the heart of the device. The procedure is the same as described above in MOD8, and the keys available in this mode are M1 to M4.

However, by changing an oscillation resistor, a sam- pling rate as high as 8. Another PiP would sound to denote the end of recording.

After storing the location swe need to restart the system. Next, we show the GPS to the open sky for receiving the satel- lite signal. This project would be a great fit for your railway model.

This device is designed to provide a voice based an- nouncement for the user, i.
