Abstract
Clotheslines, which are still widely utilized in the community, were still a laborious method of exposing garments to sunshine and recovering clothes. Rain is another factor to consider, and it is difficult to anticipate. Furthermore, the amount of time and when the clothing is exposed to sunlight are manually assessed or determined by the garment’s owner. The researchers employed the prototyping model technique to create a microcontroller-based clothesline mechanism with a mobile user interface application based on these manual methods. The prototype in this study uses bluetooth wireless technology to connect the user interface of the mobile application to the clothesline controller, which can manually extend and retract the clothesline cylinder. The prototype also offers the option to schedule the cylinder's retracking using a mobile user interface application in order to maintain the suspended clothing beneath the predetermined ceiling. When rains contact the water sensor, a buzzer put beside the controller box of the prototype will be engaged and continually buzz up for a couple of seconds to warn the homeowner and the clothesline cylinder will be retracted by the motor automatically as well. Three push buttons were also added to operate the cylinder mechanisms extend, retract, and stop functions. Test cases were chosen and validated according to the hardware and mobile user interface functions described in appendix A and B to check both hardware and mobile user interface functionalities. Additionally, the Smart Sinampay can be a general type of hanger for any products that involve sunlight exposure. The mobile application and system prototype have a series of test cases. The researchers executed 10 trials of each of the device functionalities to assure that met the objectives and system requirements. The researchers used evolutionary prototyping as a guide to complete the Smart Sinampay prototype and its mobile application.
