This is a 3D printed fish feeder, this food moved from the insert to the output using a spiral. The spiral is being rotated by a small stepper motor that is connected to an ESP8266.
This controller splits the power to terminal blocks and could control four 5V devices, a 12V fan, a stepper motor and 230VAC light.
This is my first robot I made, it is inspired by bob. I first made this with the Arduino uno but it was too heavy for the servo's so I putted a Arduino mini on it.
