Server Rack temperature controlled vent blower

the code, schematic, and PDF for the rack enclosure CAD drawing are all on my GitHub.

it uses an Arduino Mega 2560, BTS7960 motor controller, adafruit Si7021 temp/humidity sensor, BV4243 display/control panel, and a salvaged camper furnace blower fan.

the only known bug is that the configuration either does not save, or it does not read in. i will post updates as i have them.

it has been a while since i posted a project, so be easy on me :wink:
