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.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
