Anthropomorphizing a houseplant with Arduino

Plants certainly add a nice ambiance to the environment, but at the end of the day, you can’t really “connect” with them as you do with a pet. As a solution to this problem, Gediminas Kirdeikis decided to anthropomorphize his houseplant using an Arduino Nano, along with a moisture sensor and an OLED display.

When the Tamagotchi-like setup detects that the soil has been watered, a happy animation is played on the screen; conversely, a sad animation is shown when dry. Electronics are integrated into a custom pot, 3D-printed in two sections. This gives the project a nice clean look, with a USB cable implemented to provide power.
