The code is an Arduino project for the Digispark Attiny85 to turn on a light source when the PIR sensor detects something. Note that after powering the PIR sensor module, it needs about 10 to 60 ...

If you can install a conventional outdoor light fixture, you can install a motion sensor light, although aiming and adjusting it takes extra effort.

Instructables user VeryEvilBetty details this project, which requires the LED strips, a light sensor, and an arduino controller. Code is included so you can make your own automatic nightlight ...
