The Spark Core is small, low power, and does all the heavy WiFi lifting, but will still let you do all kinds of tinkering to get your IoT project up and running. There’s a backend website platform ‘cloud’ that will let you send and receive data so, rather than having to access everything from your local network or trying to figure out how to tunnel into it, the Spark Core connects out to the Spark.io network for seamless connectivity. You can always set up your own protocols if you want, but you don’t have to. And that’s kind of the point! The Spark Core ships hooked up the cloud, so you can worry about your things and how they integrate, instead of worrying about getting the cloud to work.
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.
