SOUND TEST AUTOMATION WITH ARDUINO MEGA 2560

Abstract

At PT. X, there are several tests to check the quality of their product. One of the tests is sound testing and applied for electronic product, which produce sound. The test is done for about a thousand times every month and done manually by the operators. Every operator handle about six products, they push the button of the product and then hear the sound come out from it, then make a check list on the paper until a thousand times. PT. X not considered this type of testing as dangerous, however, the task will create a fatigue due to repetitive movements and hearing noises (sound coming from the products) for hours. From these points of view, the idea to design and to implement a “Sound Tester Automation” came up. This final project concentrates in designing the hardware and the software that will work as an integrated system of circuit that has the sound analyzer function. The circuit also has other function which is the press button automation. Through those function, the user of the circuit will be able to adjust the length of time of the sound and adjust the counter for the press button automation. Both sound analyzer and press button automation functions are combined to work together. Hence, when the sound analyzer works, then it will send signal to the microcontroller, if the sound is on then the press button automation continue to work, but if the sound is off, then the buzzer will turn on and the LCD will show a sign.
