What is the first example of physical computing? It might be the from two millennia ago. Here’s more from the UK Science Museum:
The mechanism, then a calcified lump, turned out to be an agglomeration of corroded bronze gearwheels, dials and inscriptions that has puzzled, intrigued and amazed scientists ever since…. Today the Antikythera mechanism is considered one of the wonders of the ancient world and has challenged all preconceptions about the technological capabilities of the ancient Greeks.
‘It has been clear since it was brought up from the sea that it is unique – there is nothing else like it in the historical record, and it would rewrite the history of technology,’ said Jo Marchant, author of Decoding the Heavens: Solving the Mystery of the World’s First Computer.‘ But it has taken more than a century to figure out exactly what it did and how.’

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.
