I Made a Smart Motion Detector Alarm With SMS Alerts — and you can too

Imagine getting an instant text the moment someone steps into your space — and knowing you built the system yourself. With just an Arduino, a few affordable components, and my 37-page step-by-step booklet, you’ll learn the exact wiring and coding to create a smart motion alarm that works anywhere. Build it in a weekend, gain skills you’ll use for life, and enjoy the satisfaction of saying, “I made that.” The link is in the downloadable files — and if you’d like to support my work, you can do so through it.
