Electronic Mailbox Designed with FPGA Platform

Abstract

An electronic mailbox is a device proposed to detect letter delivered by postman when the mailbox is opened or closed to notify the user for their new mail. The goal of this work is to make a mailbox model that can calculate the amount of mailbox opened by postman and lights up the yellow or red LED and buzz the buzzer to indicate an existing mail inside the mailbox. It is design to demonstrate the feasibility of using a Field Programmable Gate Array (FPGA) to implement custom hardware functionality. The present hardware consists of an infrared sensor (IR), a buzzer, seven segment display, FPGA and pushbuttons. This research paper demonstrates our proposed ideas, describes the design of a smart mailbox, the prototype, and the current results of work.
