So you would like to build your own internet connected automatic pet feeder? Ntrobotics has just the project to give you a few ideas. It involves 3D printing the body and using an Adafruit Feather HUZZAH with ESP8266 WiFi to control the device. The mechanism is driven by a Continuous Rotation Micro Servo – FS90R.
You are going to need simple tools such as a hot glue gun, soldering iron, and wire stripper to complete this project.
