A Pet Feeder witch ESP8266 chip

Recently I made a pet feeder for my cat. I also made a detailed step-by-step description of this project and its integration with HA if someone wants to do it yourself.
You can download all files like schematic, STLs, GERBERs, and BOM for it.

EDIT: I made a Youtube video about this project. I put the link at the very top.
