From Team Plant Protector: Brian Cottrell, Christine Cottrell, Joe Gonzalez, Ruby Hsu, Chih-Wei Hsu on Hackster.io:
In order to efficiently distribute water and nutrients to our plants regardless of the shape or size of the planter, we place a small inexpensive ultrasonic humidifier into a 3D-printed enclosure so that it would fit in the base of the planter and allow air to flow inside so that it could be pushed through the vaporized fluid and into the interior of the planter.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
