In our last post we discussed on how to monitor Saline level using an LDR, now let us move to the APR module. Before going to the interface part of APR 9600 with the microcontroller, lets look about APR9600 in brief.
The APR 9600 is a 28 pin device used to record and playback maximum of 8 messages. The APR9600 device offers true single-chip voice recording, non-volatile storage, and playback capability for 40 to 60 seconds. The device supports both random and sequential access of multiple messages. Sample rates are user-selectable, allowing designers to customize their design for unique quality and storage time needs. Integrated output amplifier, microphone amplifier, and AGC circuits greatly simplify system design. The device is ideal for use in portable voice recorders, toys, and many other consumer and industrial applications.
