SciShow (previously) host Hank Green explains the differences between the concepts of “zero g” and “zero gravity.” It’s an important distinction, so far as the basic workings of the Universe are concerned.
Zero G does not truly mean zero gravity, because there is gravity everywhere. If there were truly no gravity, plants and stars wouldn’t even form, let alone orbit around each other.
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.
