PIR sensor, etc. Default pinout: Pin 9 - main output. That's where you connect your LEDs. Of course you can change that but remember: not all pins on arduino support PWM! Pin 13 - RLED output. When ...

WS2812B addressable led string usually comes in a strip of 30 LEDs. I put 2 LEDs per stair which gave me 2-spare pairs in case an led pair needs to be replaced. It currently requires FastLED 3.1 ...

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 ...

Proximity sensing is a common application for intruder alarms, light switches, and other home and industrial automation applications. There are multiple methods of proximity detection used in the ...

Here is a simple and inexpensive Arduino based motion sensor alarm with voice alert. It can be used for security purposes. Typically, for outdoor monitoring, motion sensor alarm consists of a PIR ...
