Smartdoor Prototype Using Arduino and Amr Voice?

Since it was announced by the President of the Republic of Indonesia on March 2, 2020, regarding the discovery of Covid 19 or corona cases in Indonesia, cases of corona sufferers have increased and spread to all corners of Indonesia. One of the characteristics of the Corona Virus is that it survives on the surface of objects held by the exposed person. Therefore, avoiding contact with objects that are shared is one way to prevent the spread of this virus. The gate and front door of the house are the most vulnerable objects as a place for the Corona virus to spread. This is because the gate and front door of the house are located outside the house and are in direct contact with many people passing by. Microcontroller technology combined with a sound sensor via Bluetooth connection can function as an automatic door opening and closing lock that can prevent users from touching when they have to open the door.
