A simple Python script which turns your Raspberry Pi into a motion activated nightlight.
You will need the following dependencies:
pip3 install RPi.GPIO rpi-ws281x
Clone this repo or just download the python script and put it into /usr/local/bin for example and make it executeable.
chmod +x /usr/local/bin/nightlight.py
Probably you want to start this script at boot, put this in /etc/cron.d/nightlight
@reboot root /usr/local/bin/nightlight.py > /dev/null 2>&1
Connect the PIR sensor as following (I have used a HC-SR501):
VCC: 5V
DATA: GPIO 23
GND: GND
Connect the Neopixel strip (some ws281x will do) as following:
VCC: 5V
DATA: GPIO 18
GND: GND
