Reading the graph above is pretty obvious. It plots the temperature of the DS18B20 sensor connected to the Raspberry PI vs. the outside temperature that is provided by a local weather forecast feed. Just for fun, we also display Min and Max temperatures (which can be reset).

The graphing is provided by sen.se. The sen.se site offers a lot of flexibility with “the internet of things”. sen.se is free. Sign up and scan the tutorials. The site is well laid out and the tutorials are very straight forward; you’ll be an expect in no time.
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.
