I regularly hear complaints that git submodules are difficult to work with. If you search for ‘git submodules’, then (depending on your filter bubble) you’ll probably get several blog articles warning you not to use them. I agree that the UI is not at all intuitive,1 but like most things in git, submodules are quite simple under the hood. In this post I’ll share the incantations for solving some specific submodule problems, and try to shed some light on what’s really going on.
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.
