NeoPill is the NeoPixel Emulator You’ve Always Wanted.

NeoPixels and other addressable LED strings are a technology that have made vibrant, glowing LED projects accessible to all. Of course, it’s nice to be able to simulate your new glowy project in software before you actually set up your LED strings in practice. [Randy Elwin]’s NeoPill simulator can help with that!

The NeoPill consists of an STM32F103 development board, into which one simply hooks up a NeoPixel data line. The microcontroller then decodes the data using a combination of its onboard timers and SPI hardware. This data is then passed to a PC over the onboard USB serial connection, where it’s decoded by a custom Python app. The app takes the data and displays the pixels on screen, so you can verify they operate as expected before you hook up a single real LED.

Arduino IR – Control LEDs with Arduino remote control [Using 1838 ir sensor]

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.

Turn your staircase into a flaircase with this LED system

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.

These side glow fiber optic panels make beautiful wall décor

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.

DIY Color Changing Acrylic Nightlight using ATtiny85 Microcontroller and Arduino

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 RGB LED Accent Light

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.
