Woha! - :link: [Galactic Unicorn store page](https://shop.pimoroni.com/products/galactic-unicorn) Galactic Unicorn ships with MicroPython firmware pre-loaded, but you can download the most recent version at the link below (you'll want the `galactic-unicorn` image). - [MicroPython releases](https://github.com/pimoroni/pimoroni-pico/releases) - [Installing MicroPython](../../../setting-up-micropython.md) ## Galactic Unicorn and PicoGraphics The easiest way to start displaying cool stuff on Galactic Unicorn is using our Galactic Unicorn module (which contains a bunch of helpful functions for interacting with the buttons, adjusting brightness and suchlike) and our PicoGraphics library, which is chock full of useful functions for drawing on the LED matrix. - [Galactic Unicorn function reference](../../modules/galactic_unicorn/README.md) - [PicoGraphics function reference](../../modules/picographics/README.md) ## Examples ### Clock [clock.py](clock.py) Clock example with (optional) NTP synchronization. You can adjust the brightness with LUX + and -, and resync the time by pressing A. ### Eighties Super Computer [eighties_super_computer.py](eighties_super_computer.py) Random LEDs blink on and off mimicing the look of a movie super computer doing its work in the eighties. You can adjust the brightness with LUX + and -. ### Feature Test [feature_test.py](feature_test.py) Displays some text, gradients and colours and demonstrates button use. You can adjust the brightness with LUX + and -. ### Feature Test With Audio [feature_test_with_audio.py](feature_test_with_audio.py) Displays some text, gradients and colours and demonstrates button use. Also demonstrates some of the audio / synth features. - Button A plays a synth tune - Button B plays a solo channel of the synth tune - Button C plays a sinewave (it's frequency can be adjusted with VOL + and -) - Button D plays a second sinewave (it's frequency can be adjusted with LUX + and -) - Sleep button stops the sounds ### Fire Effect [fire_effect.py](fire_effect.py) A pretty, procedural fire effect. Switch between landscape fire and vertical fire using the A and B buttons! You can adjust the brightness with LUX + and -. ### Lava Lamp [lava_lamp.py](lava_lamp.py) A 70s-tastic, procedural rainbow lava lamp. You can adjust the brightness with LUX + and -. ### Nostalgia Prompt [nostalgia_prompt.py](nostalgia_prompt.py) A collection of copies of classic terminal styles including C64, MS-DOS, Spectrum, and more. Images and text are drawn pixel by pixel from a pattern of Os and Xs. You can adjust the brightness with LUX + and -. ### Rainbow [rainbow.py](rainbow.py) Some good old fashioned rainbows! You can adjust the cycling speed with A and B, stripe width with C and D, hue with VOL + and -, and the brightness with LUX + and -. The sleep button stops the animation (can be started again with A or B). ### Scrolling Text [scrolling_text.py](scrolling_text.py) Display scrolling wisdom, quotes or greetz. You can adjust the brightness with LUX + and -. ## Wireless Examples These examples need `WIFI_CONFIG.py` (from the `common` directory) to be saved to your Pico W. Open up `WIFI_CONFIG.py` in Thonny to add your wifi details (and save it when you're done). - [micropython/examples/common](../../examples/common) ### Cheerlights History [cheerlights_history.py](cheerlights_history.py) Updates one pixel every five minutes to display the most recent #Cheerlights colour. Discover the most popular colours over time, or use it as an avant garde (but colourful) 53 hour clock! Find out more about the Cheerlights API at https://cheerlights.com/ Requires `WIFI_CONFIG.py` and `network_manager.py` from the `common` directory. You can adjust the brightness with LUX + and -. ### Galactic Paint [galactic_paint](galactic_paint) Draw on your Galactic Unicorn from another device in real time, over wifi! Requires `WIFI_CONFIG.py` from the `common` directory. It also needs the `micropython-phew` and `microdot` libraries (you can install these using Thonny's 'Tools > Manage Packages'). ## Other Examples ### Launch (Demo Reel) [launch](launch) If you want to get the demo reel that Galactic Unicorn ships with back, copy the contents of this `launch` folder to your Pico W.
