How humid is my apartment right now? Let me text my FONA!
In this guide, you will build a text-able environmental monitor using the Adafruit FONA shield, a Metro M0/M4 development board and a Bosch BME280 precision sensor. Using CircuitPython, the Feather can send and receive SMS messages using the CircuitPython FONA library and read environmental data from the BME280 sensor with the CircuitPython BME280 library.
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.
