Carderly

Connecting to raspberry pi on windows

• Connect the raspi by changing the wpa_supplicant.conf wifi parameters in boot of the sd card
• Install putty and advanced IP scanner on your computer
• Once sd card plugged and raspi power supplied, search for IP adress using IP scanner (you should be connected to the same wifi)
• Put the IP adress on putty should open a terminal in the card
• If you want a nice display you can use windows remote desktop and put the same IP adress It can work by ethernet but I never tried

Magic Command for the raspberry pi

$ sudo raspi-config

Goes to the config menu of the card.

$ ifconfig

Shows IP adresses and connectivity

$ sudo apt-get <module name>

Install some module in general but always look at the documentation first

du -h
df -h
free -h

Three different commands to check used memory, free memory and RAM (-h means human readible format of numbers)
