I want to light up my stairs with a motion detector light or switch to start the lights when somebody walks up or down.
Any guide or tutorial available out there that could help me with it ?

You might mount a photo-sensor in a position where someone walking by will change the light level.

Amplify the output and send it to trigger a timer circuit, which will switch on a light for 5 minutes (or whatever you wish).

As for the light, a single bright white LED could be sufficient. However if you want to turn on 120VAC to a lamp, then a relay is the convenient method.
