On January 23, 2019, the Cleveland Museum of Art (CMA) announced over 31,000 digital images of artwork from its collection will be available in the public domain. There are dozens of art types included in the collection, including paintings, drawings, photographs, coins and jewelry. All of these images are available under the Creative Commons Zero (CC0) license, which allows people to share, collaborate, remix, and reuse images from the collection for both commercial and non-commercial use. The CMA also created a free API that allows programs to easily retrieve information about each of these images.
This no solder project accesses the CMA API using CircuitPython running on an Adafruit PyPortal. It uses the API to pick a random item from the collection. It converts and resizes the JPEG image from the collection to a BMP image sized to the PyPortal using Adafruit IO image conversion service. Finally, the converted image is downloaded to the PyPortal for display. A new feature of the PyPortal allows the correct scaling of portrait images, which is a great feature for this project.
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
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.
