This document describes the design of an automated seed sowing machine controlled via Bluetooth. The system uses an Arduino microcontroller connected to a Bluetooth module to receive signals from a mobile app. It also includes components like a solar panel, motor drivers, motors, pump, and relay to automate the seed sowing process. The device is aimed at improving efficiency in the agriculture sector by automating planting tasks and helping address the lack of skilled labor.

2. ABSTRACT
This project is focused on an agriculture seed sowing
process controlled by using Bluetooth. In digital India
technology, it plays a vital role which include Agro-
technology which the method of applying the
technology innovation occurring in daily life which can
be applied to agriculture sector causes to improve the
efficiency of the product (rice, wheat, maize, etc.) and
can help to develop better seed sowing machine to help
the agricultural field

3. INTRODUCTION
Agriculture has been the backbone of the Indian economy and
will continue to remain so for a long time and 70% of
people depend on agriculture. It has to support almost 17
percent of world population from 2.3 percent of world
geographical area and 4.2 percent of world’s water resources.
Currently in most of the countries, the skilled man power in
agriculture sector is absent and that effect the
growth of developing countries. Autonomous agricultural
robots are an alternative to the tractors found on fields today.
Cultivation tasks like seeding, spraying, fertilizing and
harvesting may be performed by fleets of autonomous
agricultural robots in the future.

7. The Arduino Uno is an open-
source microcontroller board
based on the Microchip
ATmega328P microcontroller
and developed by Arduino.cc.
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.

9. THE WORKING PRINCIPLE
OF ELECTROMAGNETIC RELAYS IS NOT
COMPLICATED, AND IT OPERATES
MAINLY ACCORDING TO THE PRINCIPLE
OF ELECTROMAGNETIC INDUCTION.
SWITCHING ON THE POWER IN THE LOW-
VOLTAGE CONTROL CIRCUIT, THE
CURRENT GOES THROUGH THE COIL OF
THE ELECTROMAGNET TO GENERATE A
MAGNETIC FIELD.
IN THIS PROJECT RELAY WILL BE USED

10. PUMP
The main advantage of DC (direct
current) pumps over AC (alternating
current) pumps is that they can operate
directly from a battery, making them
more convenient and portable. ...
However, AC pumps usually are
designed for higher speeds and larger
bursts of power.

11. Solar panel
Solar panels are devices that
convert light into electricity. They
are called "solar" panels because
most of the time, the most
powerful source of light available
is the Sun, called Sol by
astronomers. ... A solar panel is a
collection of solar cells.

12. Motor driver –l293d
L293D is a typical Motor driver or
Motor Driver IC which allows DC
motor to drive on either direction.
L293D is a 16-pin IC which can
control a set of two DC motors
simultaneously in any direction. It
means that you can control two DC
motor with a single L293D IC.
