1. Planning and Design: Start by identifying the requirements, such as where the motion sensors and lights will be placed. A common design includes sensors at the top and bottom of the stairs, and LED strip lights along each step or under the railing.
2.Component Selection: Choose appropriate components like motion sensors (PIR or ultrasonic), a microcontroller (e.g., Arduino), LED lights, a power supply, and connecting wires. Optional components include a relay module or transistor circuit for controlling the lights.
3.Circuit Assembly: Connect the motion sensors to the microcontroller’s input pins and the lights to the output pins via a switching circuit. Ensure that the power supply is compatible with the voltage requirements of both the lights and the microcontroller.
4.Programming: Write a program for the microcontroller that detects motion and activates the lights accordingly. For example, if motion is detected at the bottom of the stairs, the lights gradually turn on step-by-step going upwards.
5.Installation: Secure all components in place—sensors at entry points, lights along the stairway, and the microcontroller in a protected but accessible location.
6.Testing and Calibration: Test the system to ensure it responds accurately to motion and adjusts the light timing and sensitivity as needed.
