SSh and putty


SSH is secure shell this is a protocol built into the raspberry pi, this gives the user the ability to access the lx terminal via a different computer on the same network. This is secure communication between two devices over an insecure network.

 

Simple software for this is Putty; this recreates a terminal screen on your P.C via this SSH allowing for wireless (in our case) control of the raspberry pi. This allows for us to remove the keyboard, mouse, USB hubs etc. from the Pi allowing for much lower power consumption. This gave us the idea not only to control the Pi wirelessly but also make the raspberry Pi portable.

 

This turned out to be a success and via the putty terminal we can manually control the GPIO terminals and also power the raspberry pi via a portable battery cell.

 

Below is a video of this being achieved.
