Light up stairs as you walk, need sensor advice
i have spiral staircase.
i have strips of leds under each stair, when walks stairs, lights underneith of each stair step on it. sensor simplest?
there 15 stairs, can arduino take 15 inputs?

15 inputs, yes can. uno has 14 digital pins (12 if want use serial monitor) , 6 analog pins, can digital in/outputs.
the best way save pins use shift register led strips , multiplexer sensors.
as far sensors, go can have pressure, ir or ultrasonic sensors.
what spending budget? different types of sensors cost more others , need 15.
