Controlling Addressable LED's

3_pin_vs_4_pin_interrupts

Anonymous (anonymous@undisclosed.example.com) — 2018-11-10T14:27:51+0000

3 Pin Addressable LED's These are primarily the WS2811, WS2812, WS2812B or NeoPixel series of LED's. * These are inexpensive compared to 4 pin strips. * You can use several pins to drive multiple strips with them. * The disadvantage is that FastLED disables interrupts, so you can't use libraries that rely on interrupts (such as IR remote) at the same time on an 8 bit AVR.

It's been a painful period of learning, and several of my lanterns were damaged due to rain. For the longest time, I was just using watered down white glue and white wrapping tissue. The first layer ripped and tore, but eventually held. It got easier from there.

There are two main types of bamboo for lanterns: * 1/2“ wide (as used in blinds) * Outer peel is about 1/4” wide You can soak the regular blind bamboo in order to create shapes. The outer peel is stiffer and less pliable than the wider bamboo. In Vancouver, good stores are Jysk and Coolite (at Hastings and Campbell).

Writing Code * Learn how to code and learn the basics of (FastLED) first. There's lots of examples online. * Break it down into individual components (i.e. buttons, IR, LED's, Bluetooth, serial communications, demo sequences). * Create test 'jigs' and programs for each component.

diffusers

Anonymous (anonymous@undisclosed.example.com) — 2018-11-10T14:36:18+0000

LED lighting can be made more 'magical' by adding an element of diffusion. Traditional lanterns use paint or coloured paper in conjunction with a candle. When using addressable LED's, you may want to let the LED's add that colour instead. As a result, when looking for materials for diffusion, you may want to focus on translucent white materials.

External Inputs In order to use external controls, such as a pushbutton or infrared receiver, please keep in mind the following: FastLED will disable interrupts in order to drive 3 pin strips, such as the WS2812, thus wreaking havoc on libraries that rely on them, such as Infrared.

Here's a VERY simple routine to see what you've got everything working: #include "FastLED.h" #define NUM_LEDS 20 CRGB leds[NUM_LEDS]; void setup() { FastLED.addLeds(leds, NUM_LEDS); } void loop() { leds[0] = CRGB::White; FastLED.show(); delay(10); leds[0] = CRGB::Black; FastLED.show(); delay(10); }

The two most popular types of addressable LED strips are WS2812's aka NeoPixels and APA102's aka DotStars. The latter names are from Adafruit. Here's their comparison guide: Reference: * 3 Pin Addressable LED's These are primarily the WS2811, WS2812, WS2812B or NeoPixel series of LED's.

Power Management If you want to ensure you don't overload your battery, you might want to use power managed displayp put the following in setup(): set_max_power_in_volts_and_milliamps(5, 500); This is used by the power management functionality and will limit the brightness of your LED's to draw up to 500mA.

Powering Small Projects Reference: If you are connecting the Arduino to your computer and have a small strip of LED's, let's say <20, you can power them directly from the USB port: Alternatively, with an Arduino UNO, you can power from the 7-12V input (preferably closer to 7). You could also provide a 5V power supply, and connect that directly to the 5V pin on the Arduino.

Vixen Lights is a popular free software package which allows users to create lighting effects with a wide range of display technologies. Here, we'll provide 2 ways on using Vixen Lights with addressable LED's: * Vixen Lights sends the entire display sequences to an Arduino for display on the LED's. * Vixen Lights sends commands to the Arduino, which then sends FastLED display sequences to the LED's.
