PCB light painting night light: a perfect combination of art and technology to illuminate the darkest path in life.

Foreword:
As an elderly person groping in the dark, I often stumble and fall. So, I made a small nightlight to illuminate my path.

Schematic Diagram: The
schematic diagram mainly consists of three parts: power supply, sensors, and LEDs. The sensors include pyroelectric infrared sensors and photoresistors. All modules are connected using connectors. This project does not require software; all control logic is implemented in hardware.
 
PCB
: This is the third part of the PCB diagram. I spent a long time working on the window openings; my hands were trembling.
 
Actual Product:
This is the soldered circuit board. The yellow parts are the windows used for light transmission. Since the components are connected via connectors, you need to solder the wires yourself.
 
 
 
Casing:
I used 3D printing from FLCSC. It's best to choose an opaque material for the casing. After the casing is printed, a reflective film must be attached to the back panel during assembly; otherwise, the light will be uneven. The reflective film is simply a piece of white paper.
