Smart Automatic Pet Feeder

This is the best open source pet feeder available.

This took DOZENS of models, iterations, and software debugging to perfect.

However, I am an amateur, please feel free to adapt and improve as you see fit!

Please share your improvements so we can build a community behind this!

Instructions PDF is attached

It includes all the required materials, circuit diagram, and build guide.

Here is a link to the code for the ESP32:

WIFI setup should be automatic. 

Just use the provided code. When powered an not connected to WIFI the ESP32 will create a WIFI network called “BurritoFeedo_Setup”.

Connect to that with a mobile device and it will open a prompt to enter your home WIFI network credentials! This only needs to be done once. 

All parameters including WIFI, feed weight, and times are saved to non-volatile memory on the device. 

After ESP32 is connected to WIFI just go to catfeeder.local on your mobile device (while also connected to your home WIFI) to open the web app and control it!

Sorry I forgot to list the bowl that I designed this around, it fits perfectly in the machine. I got a 4 pack so I can replace it while I clean the old one.

Forgot to include a resistor in the circuit diagram! I used a 400 OHM resistor that came with the LEDs I included on the BOM. You can use a pretty wide range of resistors and it will still function, a higher resistor value will just significantly extend the LEDs lifetime in exchange for brightness. (400 OHM is ideal)
