This kit guides you through creating a motion-activated LED strip that illuminates a staircase for 30 seconds - exactly when an elderly family member steps near. No more fumbling for switches in the dark. You'll use a PIR sensor to detect movement, an Arduino to process the signal, and a relay to switch the lights on for a precise, timed interval, all while learning real-world automation.\u003c\/p\u003e\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eYou'll assemble a working safety light system that mounts near any staircase. When the PIR senses motion, five bright white LEDs turn on automatically and stay lit for half a minute, giving enough time for a senior to ascend or descend safely. The relay isolates the low-voltage control from the output, a technique used in countless home automation devices.\u003c\/p\u003e\n\u003ch2\u003eWhat You'll Learn\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eWiring a PIR motion sensor to an Arduino input pin\u003c\/li\u003e\n  \u003cli\u003eProgramming an Arduino to trigger a relay based on sensor signals\u003c\/li\u003e\n  \u003cli\u003eUsing the delay() function to create a precise 30-second timer\u003c\/li\u003e\n  \u003cli\u003eDesigning a practical elder-care device from individual components\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eKit Contents\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eComponent\u003c\/th\u003e\n\u003cth\u003eQuantity\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eArduino Uno R3\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eHC-SR501 PIR\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e5V Relay Module\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e5mm White LED\u003c\/td\u003e\n\u003ctd\u003e5\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e1N4007 Diode\u003c\/td\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e10k?
