Limor Fried is the founder and engineer behind Adafruit Industries which makes electronics kits that teach soldering, tinkering, and technology exploration. One of their projects, the Tweet-a-Watt, is a wireless modification to a common off-the-shelf home energy monitor, the Kill-a-Watt. The Tweet-a-Watt not only monitors your energy consumption, it sends the information to Twitter so you can track it online, which reveals usage trends over time. Besides selling a Tweet-a-Watt kit, Adafruit has also put the open source plans online for all to freely build and share, creating a network of makers watching their usage and swapping energy-saving tips.
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.
