{"abstract":"For elders and PWDs, it is sometimes arduous for them to reach the switch of the light and turn it on. Hence, innovating new and unique light bulbs might help them and it can be favorable for students, children, and the elderly. This study aimed to create a 2-in-1 motion and sound-powered desk lamp in terms of detecting different hand motions and sound sources. The device was assembled by programming the code of the Arduino. Different wires served their purpose and were then connected to the Arduino. Quantitative observation was utilized in this study in which a series of testing was conducted to determine the sound and motion sensitivity of the 2-in-1 motion and sound-powered desk lamp. The results showed that the motion and sound sensitivity were both rated excellent in turning the device on by 5 different hand motions (back and forth vertical and horizontal handwave motion, raising the front and back parts of the hand, pushing the palm towards the sensor, and peace sign hand gesture) and 3 specified sound sources (handclap, knocking, and tapping an object) The study concluded that the 2-in-1 motion and sound Powered desk lamp has a high sound and motion sensitivity which enables it to emit light automatically.","abstract_source":"original","authors":["Mutmainna Adam","Guiazim Abas","Princess Kaye Moquete","Alnoury Cauring"],"date":"2023-09-26","doi":"10.5281/zenodo.8380119","id":2036,"issue":10,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"15d81612e34bb55efb9d0852aec2e3d5fc49316998dbcbbabaa7fa4b1d3c00d7","schema":"scimatic-article/1","title":"2-In-1 Motion And Sound Powered Desk Lamp","volume":13}
