3. Introduction
• Food and feeding are the important elements for
growth of fish.
• An automatic fish feeder is an electronic device
that is designed to feed fish at regular intervals.
• This project aim to design a fish feeder system
using Arduino.
• and also to monitor water quality using
various sensors

4. OBJECTIVE
The objective of this project is
 To design and fabricate fish feeder system.
 To enable fish owner to customize feeding time
 to check water quality

5. PROBLEM STATEMENT
1.Quantity of food dispersed.
2.Lack of real-time monitoring.

6. PREVIOUS WORK
The automatic fish feeder system, All in One
Box”Aquarium Feeder using 8052 with manual
setup which was created by BrianLaebens on
2014 .

7. DRAWBACKS
• The user have to program the machine using the AC
timer and if the timer is broken, the fish cannot be
fed.
• Lack of real time monitoring

8. PROPOSED SYSTEM BLOCK DIAGRAM
Components
 Arduino uno
 Power supply
 DC motor
 Driver ic

DRIVER IC MOTOR
AQUARIUM
FEEDER
BOX
LCD

10. WORKING
 The supply of power to the board initializes all the hardware
components and LCD displays the welcome message.
 In order to set the times for feeding fishes the push button is
pressed. After pressing the push button the LCD prompts three
choices
1.Start date
2.Dose details
3.Change Time & Date.
 The appropriate choice is selected by the owner with the help of
4*4 keypad
 The controller turns on the DC motor to drop the food into the
aquarium if the time is matched with the set time.

11.  We do the work by following steps
  Firstly, we connect Arduino with pc
  Then connect those component with IOT server
  Connect all sensor with Arduino and Ethernet shild
  Then connect Ethernet shild with Arduino
  Then connect those component with IOT server
  Then make a website and android app and connect IOT server with
app and website by Rest-Api.
  Analyze those data and classify by a given algorithm
  Analysis and compare previous and continuous data and take
decision.

Bridge
Rectifier
Regulator
DC Output

14. SENSOR
 temperature of water will be monitored using
lm35
 odur of water will be monitored using mq2
 dissolved solids using tds sensor
 light using ldr sensor
 water recycle using motor

15. 3. DC motor
•A DC motor is any of a class of rotatory
electrical machines that converts direct current
electrical energy to mechanical energy
•It works on the principle of electromagnetism

16. 4.L293D Motor Driver :
L293D is a dual H-Bridge motor driver, so with one IC we can
interface two DC motors which can be controlled in both
clockwise and counter clockwise direction

19. Advantages
 Real time monitiring.
 Avoids food starvation and overfeeding
 The fishes can be feed even when the owner
forgets to do so.

20. DISADVANTAGES
 This system can disperse dry food only.
 This system is limited to domestic use only and
unable to function if there are no electricity or
the system is offline.

21. CONCLUSION
 The raspberry pi based fish feeder system is
designed to overcome the problem of fish dying due
to fish feeder malfunction
 This to ensure that the user will not comeback to
dead fishes because they unable to check their tank
status.
