Code for arduino that makes fade in/out effect after receiving signal from switch, PIR sensor, etc. Default pinout: Pin 9 - main output. That's where you connect your LEDs. Of course you can change ...

To detect motion using a PIR sensor connected to an Arduino and trigger an LED (using the built-in LED) when motion is sensed. Passive Infrared (PIR) sensors are electronic devices that detect motion ...

Motion detection is a common application for intruder alarms, light switches, and other home and industrial automation applications. And there are several ways to do it. We have already used a PIR ...

Street crime is very common in the modern century. Everybody needs to feel secure when they are at home either while sleeping at night or during day time. So, many security alarm systems are available ...

The complete circuit diagram for Arduino Based Decorative Christmas Tree is given above. It is pretty simple as we only need to connect a PIR sensor, JQ6500 voice module, and Neo-Pixel LED Strip. The ...

Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...

Wireless sensor networks are nothing new to Hackaday, but [Felix]’s wireless PIR sensor node is something else entirely. Rarely do we see something so well put together that’s also so well designed ...

Ambient lighting systems provide accent and subtlety to homes, and are also a favorite of designers of luxury products wishing to highlight their wares. Apple stores, for example, use white light with ...
