In this tutorial, you’ll learn about using Arduino ir remote. First, you’ll see how to connect the 1838 ir receiver with Arduino Uno and how to Find the Code for each Remote Control Button. Second, you’ll see how to use ir remote to control any device connect with Arduino LEDs, DC Motor, or any more.
If you live in a house with stairs and have to traipse up and down at night, it’s best to have some sort of light that guides you. Although a cell phone can work just fine, or you could likely activate bright overhead lighting, creator MagicManu devised an automatic and progressive solution to illuminate his path instead.
MagicManu’s system knows when someone is there using PIR sensors arranged at both ends, and only activates if it’s dark enough thanks to a photoresistor. The entire setup is controlled by an Arduino Nano, while two potentiometers adjust light sensitivity and duration of ignition.
Side glow fiber optics – unlike their cousins that efficiently transmit light from one point to another – emit a glow along the length of each strand when light is applied. This creates a beautiful effect, which Andrei Erdei implemented nicely in his wall decoration project.
Erdei’s build consists of a series of nine square frames, inside of which 3mm fiber optic strands are connected, looping gracefully from one edge to another. Each strand is lit by an addressable WS2812B LED module, under the control of an Arduino Nano.
You can see this wall installation in action in the video below, and more info on how to build your own is available on the project write-up.
In this video I create a color changing nightlight based on a famous symbol from one of my son’s favorite video games. Because space was tight, I decided to use an ATtiny microcontroller instead of an Arduino. These are very inexpensive and are a great way to shrinkify your Arduino projects. ATtiny come in multiple configurations (number of pins and amount of memory). One of the most popular is the ATtiny85 which only has 8 pins and is very small.
The CandiStick is an RGB LED accent light for your home or office, turn any space into a cool relaxing light scape or even a party! There are several built in lighting effects, as well as a range of customizable colors and effects.
Each CandStick has 60 RGB LEDs, showing a full range of vivid colors and is made of light weight yet elegant aluminum and custom 3D printed modules.
