While time travel is generally regarded as little more than a plot narrative for science fiction romps, it is actually a question of some interest to both scientists and philosophers. There is nothing inherent in the known laws of physics that unequivocally prevents time travel. In fact, time travel to a distant future appears to be absolutely allowed, and we have a pretty strong understanding of how it could be accomplished, even if we don’t yet have the technology to pull it off.
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.
