I am currently doing some experiment projects with Raspberry Pi B+. In one of such experiments, I’m trying to write a python program/script which will switch on an led connected to one of the GPIO pins when the Internet connection is working fine. It is an infinite loop script which has to be run in startup so that there is no need for manually running the script. Continue reading

Install online CUPS printer in Raspberry Pi | Installing CUPS-PDF printer
