“Graphic Arrays” is about screen resolutions and aspect ratios and how these evolved over the laste decades. The left board is dedicated to more recent mobile vertical resolution ending at iPad retina. The right board represents the long history of desktop screen pixel sizes starting with the classic VGA (640×480) IBM standard from 1987 till todays common 2560×1600 desktop monsters.
Of course the DPI(PPI) has increased immensely over the years, especially with all the mobile screens recently. It feels weird to look at a 5:4 SXGA screen (1280×1024, my favorite!) today, almost portrait ration?!? At the same time when you cut a piece of paper in 16:9 format it looks super horizontal but we look at that ratio all day!
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.
