Abstract:

The applicatio is a message sending system which utilizes a sound signal detect n of IC ISD 2590or or what so-called “Mic codenser”. The detector will activate the system if a high sound signal is detected and sent to a relay which already set there. The function of the relay is to switch on a lamp on and also turn on a sound recording
system after the sound recorder is activated. In this structure the sound message recorder uses an IC ISD 2590 which able to record a sound for 90 seconds. The duration is determined by the serial number behind the name of the IC. By the only recording a sound for a few second, the IC ISD 2590 saves it an available memory voice. So, when the relay is turned on, the chip enable pin (which its ground is set in IC ISD 2590) will be immediately connected and recorded sound is played which can clearly be listened through a speaker. This therefore aims at developing the application using IC ISD 2590 and IC SN 7473 which utilizes a sound signal as its switch. The result or examination on the application system indicates that the using of logic gates is very effective and efficient because only by utilizing a digital system the switching process can be performed automatically.
