hi first time on here getting arduino don't no . trying run led lights strip stairs running off 2 small pir sensor problems signal relay when running 2 pir thinking of trying go arduino way if can me please .i have arduino uno. 2 pir sensor module hc sr501 and relay has 5v in , 240v out , 10a .plus 2a led strip lights .can wiring diagram , software program please p's 1 sensor on bottom step , 1 on top step need lights come on if going or down stairs thank
how forming question breaks , spacing can read without straining our brains make sense of paragraph.
it appears may after use 2 pirs control 2 lots of leds on stairs.
the pir treated switch low when active. code needs change of state (not looking low). leds outputs. led strings need driven relay or transistor arduino cannot control current directly output pin.
