What is this 'Arduino' thing anyway? This tutorials dives into what an Arduino is and along with Arduino projects and widgets.

Installing Arduino IDE

A step-by-step guide to installing and testing the Arduino software on Windows, Mac, and Linux.

Hardware Overview

The LED Neon Flex Rope uses the UCS1903 chipset and LEDs. The electronics are sealed in a waterproof IP65 silicone housing and diffuses the light emitting from the LEDs.

Pinout

To power or control the LED neon flex rope, you will need to connect to the female bare wire connector. 24V is required to power the LED Neon flex rope using the wire with the red stripe. The center wire is the data pin when using with a microcontroller. The third wire on the other side is for ground.

LED Neon Flex Rope Pinout

Below lists a hookup table of the pinout for reference.

LED Neon Flex Rope Pinout
Vcc (Red Striped) 24V
DAT (Middle) Data
GND (Side) Ground

LED Strip Segments

For those interested in cutting the LED neon flex rope down, you can reduce the length with the help of the colored markers on the bottom of the housing. The markers are guides and are not exact locations between the LED segments.

LED Neon Flex Rope Markers on Bottom

Each LED strip segment is about 20 inches long.

Segment Measured

Each segment uses wires to connect between each LED strip that is sealed in the housing.

If you decide to cut the strip down, make sure to seal the exposed circuit with some epoxy or hot glue.

Hardware Hookup w/ Power Only

When powering the LED neon flex rope with only power, it will display a demo. Insert the 3-prong power cable into the 24V power supply. Then make the following connections with using a female DC barrel jack adapter.

24V Power Supply Female DC Barrel Jack Adapter LED Neon Flex Rope Pinout
Center Positive + Vcc (Red Striped) = 24V
Clear (Middle) = DAT
GND - Clear (Side) = GND

Once connected, insert and fasten the adapter to the female bare wire connector into the LED neon flex rope. The setup should look like the image below. Tape was used to insulate the DAT pin since the wire was exposed.

Hardware Hookup with Only Power

Demo Mode

By connecting only to the power pins, the LED Neon Flex Rope will run a demo mode. This can include the rope cycling colors using different patterns. This can include:

  • one solid color
  • pulse and fade
  • alternating between colors
  • each segment incrementally lighting up with one color

Hardware Hookup w/ Arduino

For users that want to control the animations or react to input from a sensor, an Arduino microcontroller can be used to control the LED neon flex rope's segments. For a quick connection, we will use an alligator clip with pigtail and hookup wire.

Connecting to the DAT Pin

For initial testing, we will be using an alligator clip with pigtail to connect the LED Neon flex's DAT pin to the software defined control pin on the Arduino. Use the alligator clip to clamp on the DAT pin wire and then connect the other end to D5.

Additional Power Supply and GND Reference

Since the recommended input voltage via the barrel jack for the RedBoard is 15V, an additional power supply is required. For the scope of this tutorial, we will use the mini-USB connector on the Arduino to power the control circuit with 5V. A 5V USB port from a computer can be used during testing. A 5V USB wall adapter can be used when powering the Arduino in a project or installation.

Since we are adding an additional power supply, make sure to ground the LED neon flex rope with the control circuit. Strip a piece of wire. Then connect the "-" on the DC barrel jack adapter to the Arduino's GND pin. Wrap the wires together to make a more secure connection.

Insert Wire to GND for Reference Screw In GND Wires

Hookup Table

Based on the connections described above, here is a hookup table of the connections.

24V Power Supply Female DC Barrel Jack Adapter LED Neon Flex Rope Pinout Arduino 5V Power Supply
Center Positive + Vcc (Red striped) = 24V
5V 5V
Clear (middle wire) = DAT Pin 5 (or whatever is defined)
GND - Clear (side) = GND GND GND

The final circuit should look similar to the image below.

LED Neon Flex Rope Controlled by Arduino

Library Overview

Note: This example assumes you are using the latest version of the Arduino IDE on your desktop. If this is your first time using Arduino, please review our tutorial on installing the Arduino IDE. If you have not previously installed an Arduino library, please check out our installation guide.

To control the LED Neon Flex Rope, you could use a 5V Arduino-based microcontroller. You will need to download and install Daniel Garcia’s FastLED library using the library manager. You can also manually install it from the GitHub Repository by downloading the library from the button below.

Parameters

When using the FastLED library, certain parameters need to be adjusted to be compatible with the chipset. When using the FastLED library, the LED_TYPE would be defined as the UCS1903 chipset. There are 16 segments per LED Neon Flex Rope to control so the NUM_LEDs is 16. The COLOR_ORDER is BRG so:

red = blue
green = red
blue = green

Example Code

The FastLED library includes a few examples for a variety of addressable LED chipsets to get started. The following examples will demonstrate how to modify the example to use with the UCS1903 chipset. For more information, check out the FastLED Library's wiki.

FastLED Blink Modification

For simplicity, lets blink one segment of one LED neon flex rope using the FastLED's Blink.ino example by following the steps listed below:

  • First adjust the number of LEDs in the strip to 16.
  • Change the DATA_PIN to pin 5.
  • Comment out the CLOCK_PIN and LED arrangement for the neopixel.
  • Uncomment out the LED arrangement for the UCS1903 chipset.
  • Modify the color order by changing RGB to BRG.

Or copy and paste the modified example in an Arduino sketch. After uploading, you should see one segment blink with red.

Write code to address each segment defined in the array and reduce the delay between each blink. Or copy and paste the modified blink example in an Arduino sketch.

Color Palette Modification

Let's try modifying one more example from the Fast LED library to add the color paltette animation to the LED Neon Flex Rope light. After uploading, you should see the patterns cycling.

// This example shows several ways to set up and use 'palettes' of colors
// with FastLED.
//
// These compact palettes provide an easy way to re-colorize your

//

// run this sketch, and watch the pretty lights as you then read through
// the code.  Although this sketch has eight (or more) different color schemes,
// the entire sketch compiles down to about 6.5K on AVR.
//
// FastLED provides a few pre-configured color palettes, and makes it

// Additionl notes on FastLED compact palettes:
//
// Normally, in computer graphics, the palette (or "color lookup table")
// has 256 entries, each containing a specific 24-bit RGB color.  You can then
// index into the color palette using a simple 8-bit (one byte) value.
// A 256-entry color palette takes up 768 bytes of RAM, which on Arduino
// is quite possibly "too many" bytes.
//
// FastLED does offer traditional 256-element palettes, for setups that
// can afford the 768-byte cost in RAM.
//
// However, FastLED also offers a compact alternative.  FastLED offers
// palettes that store 16 distinct entries, but can be accessed AS IF
// they actually have 256 entries; this is accomplished by interpolating
// between the 16 explicit entries to create fifteen intermediate palette
// entries between each pair.
//
// So for example, if you set the first two explicit entries of a compact 
// palette to Green (0,255,0) and Blue (0,0,255), and then retrieved 
// the first sixteen entries from the virtual palette (of 256), you'd get
