My brother-in-law Chris wants to build a wood-fired pizza oven in his backyard. Chris is an aspiring pizza chef at night, but a process engineer by day. Although his pizza oven will be built from age old sand and clay, veins of chromium and aluminum will be running through the walls. These veins are thermocouples, a precision temperature measurement sensor. Four of these thermocouples meet back at the PiMometer, a custom-made circuit board and Raspberry Pi combo. Temperatures from throughout the oven will be displayed on a continuously updating webpage viewable from any smartphone or PC.
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.
