Normally when devices connect to the network they are assigned IP address by the router which does so sequentially (in the order of devices being connected) or randomly. The same goes with your Raspberry Pi. But if you wish to use your Pi without a display (for e.g. via SSH, as a Web Server, or any remote project) then letting the router assign a IP address is generally not a good idea. In such cases you should give your Pi a static IP so that it is always accessible on the same address. That is what we are going to do in this Instructables.
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
