Story
This PCB provides instant on/off stair lighting without fading effects – ideal for those who prefer quick, responsive light activation. Using two motion sensors (top and bottom), the circuit switches each stair's LED on or off as soon as movement is detected.
Despite its simplicity, the board offers multiple configuration options via jumpers or firmware – including night-only operation, analog or digital sensors, output hold time, and step-based activation logic. All components are easy to source, and the system runs fully standalone – no app, no WiFi.
