Automatic Pet Feeder using Arduino

Today we are building an Arduino based Automatic Pet Feeder which can automatically serve food to your pet timely. It has a DS3231 RTC (Real Time Clock) Module, which used to set time and date on which your pet should be given food. So, by setting up the time according to your pet’s eating schedule, the device drop or fill the food bowl automatically. In this circuit, we are using a 16*2 LCD to display the ...

Pet Food Dispenser featuring 4Duino-24

In this project, we will use a 4Duino and several IR sensors to create a simple pet food dispenser. 4Duino checks whether a food tray contains enough food or not. It is programmed to read IR values from each sensor. These values change depending on the amount of food in the container.  The feeding time can be set by the user via the graphical user interface. The device continuously checks the time from an N ...
