As I descend a footpath through subterranean gloom, limestone walls tower 40 feet and plunge into a chasm. Gleaming stalactites dangle from the ceiling. After several twists and turns, I reach a cul-de-sac. As I shine my iPhone flashlight on the walls, out of the darkness emerge drawings in charcoal and red ocher of woolly rhinos, mammoths and other mammals that began to die out during the Pleistocene era, about 10,000 years ago.
It feels, and even smells, like a journey into a deep hole in the earth. But this excursion is actually taking place in a giant concrete shed set in the pine-forested hills of the Ardèche Gorge in southern France. The rock walls are stone-colored mortar molded over metal scaffolding; the stalactites were fashioned from plastic and paint in a Paris atelier. Some of the wall paintings are the work of my guide, Alain Dalis, and the team of fellow artists at his studio, Arc et Os, in Montignac, north of Toulouse.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
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.
