OK now you have a Linux computer, and you are ready to make it do your bidding! We’re going to cover how to send commands to your Linux machine using the command line – you know, a line where you send commands!
In order to start typing those commands (list files! print this one out! open the web browser!) you will use a shell – a shell is a little like the Finder on Macs, or the desktop Explorer on windows but is not graphical – it uses only TEXT.
A shell is a program with a command-line interface which you talk to with a terminal. Terminals are software or hardware that let you send text back and forth to a computer. Shells offer a very specific kind of command line, but what we mean in general by that term is an interface where a user types commands and the computer responds.
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.
