  • Now there are still many announcements in classrooms that use the old system, if there are any announcements or notices heard in all areas of the school even outside the school area. So that the information submitted can be disturbing unauthorized. Therefore, we need a tool that can control the effectiveness of sound. Voice control system through an arduino uno-based smartphone is a tool that can control the sound according to user needs. This tool was made aiming to make a tool that could distribute sound to classrooms used in the UMM P2KK program. By designing a sound control circuit consisting of a controller circuit, relay circuit, and amplifier circuit so that it can control the sound needed. Arduino uno is used to read digital pins 2 to 13 that have been programmed in Arduino IDE and a computer via a serial connection. On an android smartphone there is a display of class speaker buttons in every room in the UMK P2KK. When it is on, the ON text will appear. With this tool made it easy to distribute sound to classrooms in each P2KK room as needed.
