An anatomical chart presents the hidden operating system in a graphical way, it is an educational tool that should be intelligible and attractive. Here, the anatomical chart looks like a skinned speaker, with components left visible, and signs that visually represent their technical role. The speaker cone is detached from the sheet, and spreads out to form a mechanical amplification of the sound system, and the position of the cone is also an indicator of operation. When flat, the speaker is turned off, as the folding close the circuit, creating a switch system mechanically. Co-production ISDAT
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.
