His landmark invention came after WWII ended. While on vacation, Land’s three year old daughter asked him why she couldn’t see a photo he had taken of her right away. He tried to explain to her they still needed to be developed, but that didn’t comfort her.
So Land went into the lab and created a system of one-step photography using the principle of diffusion transfer to reproduce the image recorded by the camera’s lens directly onto a photosensitive surface — which now functioned as both film and photo.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
