Cirucit for audio has been constructed. This circuit base on Apr datasheet which is the IC can be operating in many ways. There are 3 type to operate the Apr IC.
- Random Access Mode - This mode can be 2/4 or 8 message at on time.
- Tape Mode, Auto Rewind - Auto rewind the message
- Tape Mode, Normal Operation - Normal operation . 1 message at 1 time and can record over 60 sec.
For this project, the circuit for random assess mode is suitable. This caused when we need to record 4 message in different length and type.
