Use 3D-printed mounts to attach PIR motion sensors to the underside of the handrail, ensuring they can be adjusted to aim at the desired detection zones on the stairs. Route the sensor wires into the wall, joining the LED wires at the bottom of the staircase. Cut a rectangular hole in the wall large enough to house a project box. Drill appropriate holes in the project box to mount the 40A power supply and the Arduino Uno. Carefully manage all wires, feeding them into the box. This centralizes all control and power components, making them accessible for troubleshooting or future modifications.
