Cat Feeder - Part List
14/11/2021 | Views: 2430 | Arduino | by: ELECTRONOOBS      

Obviously, you will need my design for the 3D printed parts so download them from below. We have the feeder support base, the main feeder body, the hopper and finally, we have the inside feeder divider. This part will rotate inside and control the amount of foot that will get out. Together with these parts I want to use a servo motor, the MG995. We also need two bearings, a M3 threaded rod and M3 nuts. At the same time, we will also use some M3 insertion nuts for plastic. To control the servo, I will use an Arduino NANO and to get the time I will use a real time clock module based on the DS3232 IC. To supply everything, I will use a 12V DC adaptor and to get 5V I will use a buck converter. The Arduino has a 5V regulator but that is low power and I can’t supply the servo, that’s why we need an external buck converter module. You will also need glue, wires, maybe a prototyping PCB and some tools. This is pretty much all we need. Full part list is below.
