PIC compiler also supports C language code. Once the ic modu,e playing will it be playing again and again itself or it will stop after playing the recorded music 60 sec. It consists of 8 pins from D0 to D7 Port E: Press and hold the control button ii. You May Also Like.

It consists of 8 moduls from C0 to C7 Port D: 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. The given voice signal and first sampled and then the corresponding instantaneous voltage samples are stored in the non-volatile flash memory cell in 8-bit binary encoded format.

Abstract — GPS is employed to find the position of the user on the earth. An APR is a single chip voice recorder and playback device from Aplus integrated circuits. Next, we show the GPS to the open sky for receiving the satel- lite signal.

Microphone amplifier, automatic gain control AGC circuit, intends anti-aliasing filter, integrated output modupe and measure management etc. The program which is to be dumped into the microcon- troller is edited, compiled and executed. The procedure is the same as described above in MOD8, and only M1 key is available in this mode.

This project would be a great fit for your railway model. Bread- boards are great for prototyping equipment as it allows great flexibility to modify a design when needed; howev- er the final product of a project, ideally should have a neat PCB, few cables, and survive a shake test.

Leave a Reply Cancel reply. Aprr9600 we voive using eight se- lection buttons in this system we can record eight differ- ent voice messages.

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. Press the restart button iii.

Voice Recording and Play Back Circuit using APR9600

When using a double sided board we must consider which traces should be on what side of the board. PIC compiler is a software in which the machine lan- guage code is written mmodule compiled.

Proteus is a software which accepts only hex files. When making a PCB we have the option of making a single sided board, or a double sided board. This zpr9600 can be extended by incorporating a GSM module.

Voice Module 60 Sec project will playback and record up to 60 seconds of voice message. 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. Microcontroller is the heart of the device. The working of the system incorporates two stages; first the location based audio recording vlice and second, the navigation of the blind person using the signal from the GPS receiver.

Here is projects called Voice recording and play back using chip APR When we finish recording, the selection button is released. These compilers are specifically designed to meet the unique needs voce the PIC microcontroller.

Apr6900 primary use is to display the latitude and longi- tude of the current location. For recording a message we need to press the push button, followed by the selection button.

It consists of 6 pins from A0 to A5 Port B: Jumper J3 on the PCB to select audio source. My requirement is to record four different sound in one circuit and play any one sound when i want.

Check on this website http: Microphone connected to IC through couple capacitors C 3 and C 4 respectively as shown in circuit diagram. This paper describes the concept using a microcontroller based system. A double sided board is more expensive to produce professionally, more difficult to etch moeule a DIY board, but makes the layout of components a lot smaller voiec easier.

Keep the sampling rate preset PR1 in modue middle position to test a sample of the recorded message. Hi, I am apr9600 miniature railway model and I need similar circuit in which I can play pre-recorded horn by pressing button.

To achieve this mode J1 and J2 should be closed. In order to save power supply a bias signal applied to microphone while playing, the ground return of this bias network is connected to normally to open side of record switch.
