This project requiers some patience and you cannot sue me for bricking your board DO THIS AT YOUR OWN RISK!
The project is still in development.
WARNING! This project can only be used as a small linux terminal for now.
I will make a graphical version but for now that is what i can do.
For this You will need: Arduino Board, Computer, USB Cable, SD card formated FAT32 (every sd card should work), SD card reader for Computer, SD card reader for Arduino and lastly some cables to connect it.
GUIDE:
1.Download Arduino IDE from "https://www.arduino.cc/en/software/"
2.Connect your board to your computer and set it up with IDE
3.Open the file from RELEASES.
4.Upload the file.
5.Use Windows Powershell, Linux Terminal or The Serial Monitor on the IDE
For Powershell: When you launch it type "plink -serial (put your com here) -sercfg 9600,8,n,1,N", if it doesnt work install PuTTY from "https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html"
For Linux Terminal: When you launch it type "screen /dev/ttyACM0 9600" and to close use (Ctrl+A then K)
For Serial Monitor: just launch it from IDE
And thats it you have ArduinoOS on your board. Thanks for reading!
