We have a cat and when there was this contest we felt challenged to make something meaningful and necessary for our cat. Finally we had the idea to make an automatic cat feeding and drinking device. We believe it is very easy to make and suitable for cats everywhere.

Supplies

The ingredients that

prepared:

For body:

Plastic board

16 used cardboard boxes

Plastic glue

Small cable

Paper insulation

Black insulation

Mica plastic

Plastic cans

Cat food

Equipment used:

Avo meter

Pen

Scissors

Test pen

Cutter

Gas torch

Cable cutter and stripper

Match

Paper insulation

black isolation

glue gun

For electricity:

Power jack cable

5 volt cell phone charger

2 12 volt 3 Ampere adapters

2 pieces of IR sensors

2 5 volt relay modules

2 12-30 volt timer modules

2 6-12 volt dc motor dimmers

6-12 volt water pump

DC 6-12 volt gearbox motor

Step 1: Make the Drinker Body

Arrange 5 cardboard boxes according to the following picture, use plastic glue to stick them together.

Step 2: Arrange the Electricity

The electricity for this drinker is as follows:

To set the digital timer, we use the P3.2 program. We press the second button for a long time. For the operational settings, we click for 10 seconds and for the repeat settings, we click once and that's for the cat waterer.

Step 3: Make a Cat Feeder

The method :

Arrange 6 cardboard boxes, 1 plastic can, 1 balloon stick and a gearbox motor as shown in the picture by gluing the cardboard with glue.

Step 4: The Electronic Circuit for Cat Feeder

The electronic circuit for a cat feeder is as follows:

To set the digital timer, we use the P3.2 program. We press the second button for a long time. For operational settings, we click for 10 seconds and for repeat settings, we click twice and that is for the cat feeder.

Step 5: Arrange the Component of Cat Feeder

The position of components on the cat feeder

Step 6: How the Cat Waterer and Feeder Device Works

How the automatic cat drinking and feeding device works:

If the IR sensor is blocked by a part of the cat's body, for example a leg, the IR sensor will activate the 5 volt relay module. Then the 5 volt relay module activates the timer module which sends an electric current to the water pump dynamo or the cat feed roller gear dynamo. Then the water will start to fountain upwards or the cat food will be pushed out of the device and the cat can drink and eat from it.

Step 7: Cat Feeding and Drinking Utensils After Being Decorated by My Children

My children decorated the cat's feeding and drinking tools after decorating them. They decorated them with colorful impraboard. Really letting them be creative, it felt really satisfying. They finally found out how the tools work. Let's make them for our beloved cats at home because we made them very easy and simple.
