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.

Connect a appropriate speaker should not lower than 8 Ohms at LS1, Moduls playing a recorded message you just need to press and release any of the switch available in that particular mode once. 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. 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 vliceand vice- versa.
Not only is a proper PCB neater but it is also more durable as there are no cables which can yank loose.
Then, using a push button and different selection buttons we record the voice. In this system, the GPS receiver and the control buttons are the input modules to the microcontroller modulw the Voice module and the LED indicators are the output modules to the microcontroller.
An APR is a single chip voice recorder and playback device from Aplus integrated circuits. The working of the system can boice divided into two phases. The procedures is the same as described above in MOD8, and the keys available in this mode are M1 and M2. GPS based voice alert system for the blind uses the current location and gives the.

This circuit will help you record and play a 60 seconds voice message stored on it. Project Using and 4.
There is a simple process involved in recording these eight messages. In order to save power supply apr99600 bias signal applied to microphone while playing, the ground return of this bias network is connected to normally to vojce side of record switch. Please refer to http: Once the ic starts playing will it be playing again and again itself or it will stop after playing the recorded music 60 sec.
GPS provides accurate location and time informa- tion for an unlimited number of people in all weather, day and night, anywhere in the world. The only major disadvantage of this system is the time taken by the GPS to receive its initial signal from the sa- tellite, i.
APR9600 Voice Recording Playback Module Support Single Chip
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.
The first phase would involve recording of the voice in the voice module. The system designed consists of a GPS receiver and a voice circuit which is interfaced to the microcontroller. This short- ens the total length of sound recording to 32 seconds.
2 SYSTEM REQUIREMENTS
mocule When using a double sided board we must consider which traces should be on what side of the board. A Pip sound will play through the speaker to denote recording start. Also select the source for recording through CN1 Connector.
I have the Apr Google Plus and Facebook. We just have to make sure that the distance between the two locations is greater than meters. There are two different ways to record a voice message onto the chip viz.
The locations names are pre recorded in the voice circuit and are announced when the person reaches those particular locations. You can connect with me on: Currently they are some of the most popular microcontrollers, selling over million devices each year. Onboard preset PR1 will adjust the sampling rate of playback and record option for IC.
This signal is further amplifier by inbuilt pre-amplifier and by connecting pin 21 to pin 20 via an external DC locking capacitor Moduls 1. PIC16F is a 40 pin microcontroller.
