Introduction

Getting someone's attention in their office can be difficult if they are focused on work tasks (virtual meetings, training videos, etc.) and not focused on the entrance to their office. To ease the difficulty of getting someone's attention, a Cubicle Doorbell was developed utilizing the PIC16F18075 microcontroller from Microchip Technology.

This application note will explain the creation of this Cubicle Doorbell for an office setting. The doorbell system uses the PIC microcontroller's EUSART module to establish a data pipe to send data between two modules, one at the door and one at the desk.
