Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I ...

Here is an ultra simple Arduino Night Alarm project wired around a handful of inexpensive and easily available components. One advantage of using Arduino as a security system is ... LOW); ...

PIR Pin “+” connects to Arduino +5. PIR Pin “-” connects to Arduino gnd. PIR Pin “out” connects to Arduino Digital 2. Here is the Arduino code for the Parallax sensor ...

“To create this smart device, Robert used an Arduino Oplà IoT Kit, as it contains a MKR WiFi 1010, a MKR IoT Carrier with a built-in screen and capacitive buttons, and a PIR sensor for ...

For your first project, start small using one of the built-in examples in the Arduino IDE. The most beginner-friendly sketch here is the "Blink," which simply makes an LED blink.

While PIR sensors can be used with Arduino and other microcontroller boards, those best-suited for hobby use are smart enough to perform simple tasks without any programming.

[ladyada] has a freshly-published and amazingly thorough tutorial on passive infrared (PIR) motion sensors. Most often seen in security floodlights and automatic doors, in creative hands these sens… ...

Using the Arduino Sketch [Eric] has written, you can easily plug in your Wi-Fi information and IFTTT key and trigger. All that’s left to do is put this IoT motion sensor to work by mounting it ...
