Remote Controlled Pet Feeder

Introduction: Remote Controlled Pet Feeder

In this instructables i will be showing how you can build a simple Remote controlled Pet Feeder.With this simple arduino project you can feed your pet using a remote control .All you need is an Arduino Uno board(or similar),a plastic bottle,a servomotor(doesn't have to be very powerful),a TV remote ,IR Receiver(TS0P1738) and a small piece of cardboard.

Let's get Started...........

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Parts and Tools Required

  • Arduino Uno
  • Servo Motor(I've used SG90 servo motor)
  • IR receiver(TSOP1738)
  • Any TV remote
  • Jumper wires
  • Breadboard
  • Plastic bottle
  • Small piece of Cardboard


  • Scissors
  • Hot Glue gun

Step 2: Installing the IR Library

The very first thing that we need to do associating with arduino is to download the IR library.

  • Download IR library from below link and install it

If you don't know how to install a library follow below link

Step 3: Decoding IR Signals

  • First you need to connect the parts as per the given circuit diagram

  • You can checkout Pin out of TSOP1738 below

  • You can download arduino sketch for decoding IR remote or you can get it from my Github page
  • Open Arduino IDE and Upload code

  • Open Serial Monitor
  • Aim your remote at the sensor and press each button
  • you can see different numbers for each button

  • Consider any two buttons,and note down decoded values.In my case I have chosen Power button and Mode button.

I got following values

Power button=33441975

Mode button =33446055

  • we will be using this two values to control rotation of servo need to add this two values in the program which is given on next step

Let's set-up the final hardware...................

Step 4: The Final Circuit !

  1. Connect the servo's signal pin to pin#9 on the arduino
  2. connect the servo's VCC and GND pins to 5V VCC and GND on the arduino
  3. The servo will be glued to one end of the plastic bottle ,and rotate a piece of cardboard small enough to close the opening of the bottle so that the food is blocked.
  4. If all the hardware set-up is connected properly, you can simply compile and upload the sketch to the board.
  5. Now you can control your opening of pet feeder dispenser with this simple project :)

Happy Making

    It is for Cat,

    The bottle need to be fixed in one place.
