I talk to my plants. Maybe I’m crazy, but I suspect that many of you do this too. In this project, you may be able to give your plants the ability to emote back just a little bit. A.P.E.X. is basically just a moisture sensor with some emojis as a display. It isn’t overly complicated, nor even overwhelmingly necessary. This project is more of a lesson in how to build things with arduino than a helpful tool for raising plants, but if you do happen to have a really hard time judging how often to water, this might just help.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
