Creating images for the Astro-Pi HAT #piday #raspberrypi @Raspberry_Pi
Check out more info on Richard Hayler’s blog here.
My CodeClub loved their first session with the Astro-Pis. They particularly enjoyed displaying text on the LED matrix and were keen to create images like the space-invader that comes with the examples.
Obviously you can make these up directly in Python by making a list and loading it by the API, but this can be tricky in terms of colour design and involves lots of squinting.
I thought I’d try to knock up a similar application for Raspbian using pygame. There are a few programs for Windows and online that do a similar job, but I wanted something that would run natively on the Pi.
My app allows you to create patterns using the colours selected by the buttons on the righthand side.
You can then export this 8×8 pixel image to a png (filename is image8x8.png), print the corresponding Python list to the console or load it directly onto the Astro-Pi LED matrix.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
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.
