Finding petroglyphs (rock carvings) and pictographs (rock paintings) in the United States has never really been that hard. Petroglyph National Monument in Albuquerque boasts more than 25,000 images—mostly humans, animals and tribal symbols—carved into volcanic rocks by Native Americans and Spanish settlers 400 to 700 years ago, and another obvious site, Canyonlands National Park in southeastern Utah, is famously known for life-size human figures and depictions of men fighting, painted between 900 and 2,000 years ago.

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.
