Over the course of three movies, we saw Marty McFly and Doc Brown travel throughout recent human history and the near future, going as far back as the Wild West and as far forward as the unimaginably distant 2015. The Back to the Future films are fanciful science fiction comedies, not meant to be taken seriously. The science is accurate only insofar as it serves to tell a good story.
Still, is it possible to go forward and see our mistakes before they happen? Is it possible to go back and fix things that are already in our past? Here’s what we know — or think we know — about time travel.
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.
