Small info display for PC
Made using Arduino nano and python.
fetching real time info from the computer.
The thing you see behind it is a LDR with some hot glue on top to act as a ambient light sensor.
The measured brightness is sent to pc to adjust monitor's brightness and olso the backlight of the lcd is adjusted with the same.
It's using serial over usb for communicating with the pc.
The double bars are rendered using custom patch of Progressbardouble library.
[Custom library required] ---> https://github.com/P-rth/LcdProgressBarDouble
Currently only working in Linux. will only take minor changes to port to windows
Curcuit :
