Macintosh was introduced by Steve Jobs in 1984. It was the first mass-marketed personal computer that launched Apple. Much of the interface was inspired by Xerox, however they used a different system for closing windows. Instead of have the option to close a window in a drop down menu they created their own button for this. It was, however, a small rectangle on the top right of the window rather than an X. This was the first official close button. The minimize and maximize buttons were yet to come about.
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.
