Designing a device to improve your pet’s health shouldn’t come with a safety risk! We also really appreciate that spent the extra time to include a testing procedure and safety mechanism into the project. This project has a nice mix of woodworking, 3D printing, and electronics showing what can be accomplished when you aren’t afraid to mix techniques. As long as you don’t have multiple pets with the same weight, it should work just fine. While some existing solutions read the pet’s microchip or NFC collars to determine who’s at the feeder, decided against these given the fickleness of trying to reliably get a reader at the correct position relative to the pet. It seems this prototype only has one food chamber to keep unauthorized pets from eating the special food, but the basic idea should be extensible to two or more chambers. Once the pet is identified, the correct food bowl opens. The weight data is then used to identify which animal is looking for food. Using the ever-popular Arduino Uno, the feeder is connected to a platform that uses load cells to detect the pet’s weight. Facing this dilemma, set out to make a pet feeder that feeds his pets exactly what they need when they approach the feeder. If you introduce prescription foods, then this minor annoyance can have a major impact on your pet’s health. You are encouraged to further improve the code for higher efficiency and more advanced applications.If you have more than one pet, you may know how hard it is to tell how much each furry friend is eating. Hope you enjoy playing around with this project kit. Connect it to a USB power supply or battery and turn it on and let’s start feeding your pet.Note: Clean you Maker Soil Moisture sensor before you use it to feed your pet. By using a double sided tape, attach the Maker Soil Moisture Sensor to the edge of the inner wall of your pet bowl.Submerge the water pump into the cup of water then place the cup of water inside the box.Attach the entire pet feeder system to the wall or tie it to your pet cage.Flash the codes to your REKABIT, make sure that the USB data cable is connected to your REKABIT.You may find the simple explanation and description of the code at the end of this tutorial. Add the following blocks to your code.You can find those blocks in the category drawer according to their respective colours.Create several variables as listed below:.By using the same code file from Lesson 5… We have done setting up the box and let’s start to make the REKABIT to feed your pet. Notify you (in words/sound/RGB) to refill the water bottle when the water reservoir is out of water or there is no pet food left in the storage.Able to add the number of times of refilling the pet bowl either with pet food or water.Have a variable to store the information about the number of times of watering the plants.Able to fill the pet bowl with food during “meal’s time”.Able to refill the water in the pet bowl when there is no water.Able to detect whether there is water left in the pet bowl.Feed the water pump wires through the smaller hole (upper position) and into the M2 port of REKA:BIT, then tighten the wires in the motor port with a screwdriver.Feed the outlet of the water pipe through the bigger hole (lower position) of the box.Place the water pump which is connected to the water pipe in the “water cup” side of the box.Connect the Servo motor cable together with the servo extension to S1 port.Connect your Maker Soil Moisture Sensor to P2:P12 port by using the grove cable.Note: Detach the lego legs before you attach it on the box. Use 2 double sided tape to attach the REKA:BIT on the box.Let’s attach the REKA:BIT on the box and connect every component together.
