Proteus is a software which accepts only hex files. Google Plus and Facebook. While both the buttons are pressed, we hear a beep sound from the speaker, indicating that we can release the push but- ton.

The working of the system incorporates two stages; first the location based audio recording moodule and second, the navigation of the blind person using the signal from the GPS receiver. Electronic Game and Fun Projects. The module comes with a GPIO control pin for controlling the power. Not only is a proper Aor9600 neater but it is also more durable as there are no cables which can yank loose. When using a double sided board we must consider which traces should be on what side of the board.

Press the restart button iii. The microcontroller is programmed in such a way that depending on the satellite information of location the predefined location name will be announced.

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. The above disadvan- tage can be removed by using a higher efficiency GPS receiver.


Press and hold the control button ii. The recordable sound is changed to voice signal using microphone and given to IC 1 through differential amplifier. Proteus is a programmer which itself contains a microcontroller in it other than the one which is to be programmed. The term is most commonly applied to electrical energy supplies, less often to mechanical ones, and rarely to others. All normal C data types are supported along with pointers to constant arrays, fixed point decimal, and arrays of bits.

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.

Currently they are some of the most popular microcontrollers, selling over million devices each year.

APR9600 Voice Recording Playback Module Support Single Chip

I have the Apr GPS provides accurate location and time informa- tion for an unlimited number of people in all weather, day and night, anywhere in the world.

Entire 60 segment is available in a single shot mode. Complete Electrical Symbol 3. It consists of 8 pins from B0 to B7 Port C: 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.


Voice Recording and Play Back Circuit using APR9600

The system designed consists of a GPS receiver and a voice circuit which is interfaced to the microcontroller. In serial access mode, sound can be recorded in sections.

PIC16F is a 40 pin microcontroller. It should be noted that if a trace mpdule running on the top layer, check with the components to make sure you can get to its pins with a soldering iron. Pin 13, 14 are used for connecting the crystal oscillator to generate a frequency of about 20MHz.

Please refer to http: This site uses Akismet to reduce spam. Easy Electronic Projects 5. There are two different ways to record a voice message onto the chip viz. Once the machine code is converted into a hex code, that hex code has to be dumped into the microcontroller and this is done by Proteus.

Project Using and 4. Low voltage, low power DC power supply units are commonly inte- grated with the devices they supply, such as computers and household electronics.

This circuit will help you record and play a 60 seconds voice message stored on it.

Gener- ally, we put power traces on the top of the board, jump- ing only to the bottom if a part cannot be soldered onto the top plane like a relayand vice- versa. However, by changing an oscillation resistor, a sam- pling rate as high as 8. IS it interface with family?
