Plans for the case

matrix_sweep

• Arduino code to sweep LEDs across a LED matrix like https://www.adafruit.com/product/2279
• Requires Arduino Mega
• Supports three modes changed by a switch:
• Sweep a single LED through a column then over to the next row, etc.
• Sweep a whole column of LEDs row-by-row (changing color progressively)
• Illuminate the whole matrix, changing color progressively
• The speed can be adjusted by a potentiometer
• Also can control a speaker (just a piezo buzzer) with adjustable volume

Used libraries:

• https://github.com/adafruit/Adafruit-GFX-Library
• https://github.com/adafruit/RGB-matrix-Panel

AstroTracker

Barn-door tracker for astrophotography. Hardware is based off:

• https://www.thingiverse.com/thing:1133193 But the software has been extensively updated.

There are both blocking and non-blocking versions in there. For the non-blocking version, I use library:
