This is the WoPet Automatic pet feeder: https://www.amazon.com/WOPET-Automati...
I removed the controller and connected the components to a NodeMCU v1 (12E). This was a very easy modification because the WoPet device was very well engineered and uses common parts. I wrote a basic Arduino sketch to control the device and dispense food via an API call to an HTTP endpoint.
