I am tired for trying installing Arduino library in Proteus 8.6 demonstration. Please help me.
There are many websites that provide information on how to install the Arduino library in different versions of Proteus. Since I couldn't find the exact one for your version, I recommend checking the available websites listed through the Google Search page, that can be accessed below.
download any library then extract then
copy then go your c drive and go microelectronica folder and find library
folder then past.
open your Proteus and update library
