Computer users today are so attached to graphical interfaces. Sometimes it seems that people help computers to do the tasks. Can you imagine how many mouse clicks is required to do something simple. This is visible when task is cyclic like “find, sort, delete”. Sometimes you find yourself just clicking mouse and not seeing the result. What you would do half a day clicking the mouse, it can be performed with single command line. The question is how to be that smart and feel like a fish in a water in front of command prompt, shell or bash – call it how ever you want. It is a system program that accepts typed commands from used and performs tasks. If you look deeper at almost any program with graphical interface you will see that it is only a nice skin that hides same commands that run when user clicks buttons. None graphical interface can cower all features of shell commands. So if you start dealing with Linux, then start being friend to terminal.
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.
