Motor Driver (L298)** x 1 - Software: **Android Studio** ([docs](https://developer.android.com/studio)) ## Article **Introduction** The Department of posts(DOP), bartering as India post, is a government -operated postal system in India, which is a subdivision of the Ministry of communication Generally called "the Post Office" in India, it is the most widely disseminated postal system in the world. Since from 1650 the term Post office is in use shortly after the legalization of mail services in England in 1635. In India, post office are located in every villages having panchayat cities, towns and throughout geographical area in India. Post office provides various services to the public including receiving and sending letters, parcels, money orders and recently many savings services also been added like recurrence deposit(RD), PPF, postal life insurance etc. The increase of popularity of e-commerce results in a steadily increasing number of packages sent. As the population and geographic area covered increases more number of post boxes are required to collect the posts. More man power is needed to collect and distribute letters.in the existing system post man has to visit the post boxes located in every villages, cities across the India to collect the letters sometimes the post box left empty and leads to waste of effort of post man. So to reduce effort in this paper we are designing the smart post box which will notifies the admin (postmaster) regarding arrival of letters into the smart post box using IOT techniques. ## Hardware devices The hardware kit consist of an Arduino board, motor driver and Ethernet cable. The Arduino board receives the signal through Ethernet. The motor driver opens the disc. The servomotor rotates the stick and put the letter to the back of the post-box. The buttons are basically used for opening and closing of the disc. Fig 1 shows the various hardware devices used. - Arduino (UNO): The Arduino UNO is an open-source microcontroller board based on the MicrochipATmega328P microcontroller the board is equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (shields) and other circuits. - Motor Driver (L298): The Motor Driver L298N is an integrated monolithic circuit in a 15- lead Multi watt and PowerSO20 packages two enable pins are provided to enable or disable the device independently of the input signals. - Ethernet Shield: The Arduino Ethernet Shield (Figure3.3) allows an Arduino board to connect to the internet. It is based on the Wiznet W5100 ethernet chip (datasheet). The Wiznet W5100 provides a network (IP) stack capable of both TCP and UDP. It supports up to four simultaneous socket connections An Ethernet cable is one of the most common forms of network cable used on wired networks. - Servo Motor: Servo motor (Figure3.4) works on PWM (Pulse width modulation) principle, means its angle of rotation is controlled by the duration of applied pulse to its Control PIN. Basically servo motor is made up of DC motor which is controlled by a variable resistor (potentiometer) and some gears - Ultrasonic Sensor: An ultrasonic sensor is an instrument that measures the distance to an object using ultrasonic sound waves. ![](https://maker.wiznet.io/upload/ckeditor5/155723375%5F1666881979%2Epng) Ethernet Shield ![](https://maker.wiznet.io/upload/ckeditor5/155723375%5F1666882081%2Epng) Motor Drive ## Android application Android application is used to create the user interface wherein the sender and the postman can access the postbox with the help of an application. The GUI will be having open, close and count buttons wherein the open and close buttons are used for the opening and closing of the post-box and the count will show the number of letters inserted into the post-box. ## CONCLUSION The work is focused on the creation of smart post box application. We designed the smart post box which is responsible for sending the notification to the post man as well as post office admin about the arrival of posts and also the count of posts in post box. The work has many benefits mainly it reduces the effort of post man. Application notifies the presence of letters in the post box so that post man can only visit such post boxes instead of all the post boxes located in the city. will notifies the admin (postmaster) regarding arrival of letters into the smart post box using IOT techniques --- Source: https://maker.wiznet.io/Sushma_WIZnet/projects/automation-of-post-box-using-iot-technology-1/
