# Shake Away 2021 with MatrixPortal ## Overview Shake away those 2021 blues with a MatrixPortal project that will help you celebrate the end of one year, and the bright-and-shiny promise of a new year! Here are a couple of pre-compiled .UF2 files. To install, connect MatrixPortal to computer with USB cable. Double-tap the reset button, wait for **MATRIXBOOT** drive to appear and drag one of the .UF2 files to **MATRIXBOOT**. Both start with “2021” on the matrix. With a quick shake, it’s reduced to pixel sand. The first of these UF2s then switches to the glimmering “2022” after a few seconds of sand ( **six seconds** from the shake, if you’re counting down to midnight). Tap the reset button to start over.

Click **Download Project Zip** in the embed below to get both the Arduino sketch and the extra files that store the bitmaps. https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/2020_shake/2020_shake.ino The year bitmaps started as 64x32 pixel PNG images that were converted to C header files through the [media2array.py](https://github.com/adafruit/Adafruit_Media_Converters) Python script. ## Featured Products ### Adafruit Matrix Portal - CircuitPython Powered Internet Display [Adafruit Matrix Portal - CircuitPython Powered Internet Display](https://www.adafruit.com/product/4745) Folks love our [wide selection of RGB matrices](https://www.adafruit.com/category/327) and accessories, for making custom colorful LED displays... and our RGB Matrix Shields and FeatherWings can be quickly soldered together to make the wiring much easier.
