The application of BBC mikro: Bit for automatic door controller

Abstract

Automatic doors that are developed and marketed today, generally use Arduino microcontrollers as controllers. Innovations were made to obtain new components for automatic door controllers. The research was conducted to address the issue of whether British Broadcasting Corporation (BBC) micro: bits can be used as controllers to make automatic doors or not. The research objective is to obtain a new control system for automatic doors. The research method used was the design method, including designing the programming code, designing, and making automatic doors. This study's output is a prototype automatic thrust open system using a BBC micro: bit controller. The sensor used can detect objects (humans) at a distance of 0.5 - 2.5 m and height of objects ≥ 1 m. The servo motor used can turn the gears 180° to open the door. The door will open when the sensor detects an object and closes again after 2 seconds the sensor no longer detects the object. This corresponds to the programmed lag time. Based on the test results concluded, Micro: bit BBC microcontroller can be used as an automatic door controller.
