Or, as suggested by Adafruit in the Neopixel UberGuide to change the line.Īdafruit_NeoPixel strip = Adafruit_NeoPixel(60, PIN, NEO_GRB + NEO_KHZ800) Īdafruit_NeoPixel strip = Adafruit_NeoPixel(60, PIN, NEO_RGBW + NEO_KHZ800) Error messages often point towards things like - 'Serial' was not declared in this scope Serial.begin(115200).

However, when I try to adapt code to address each RGBW LED things start to go wrong.ĭepending on what I do I'll get various error messages, or the code will upload but the LEDs will be full white regardless of RGB settings. When I pull code from projects on the Adafruit site I can make the Neopixel Ring cycle through various colour animations, so things are working. I just need to create a basic code that enables me set the same colour for all the LEDs. but have run into some issues relating to code. I've been using Neopixel strips for various projects, and this time decided to use an Adafruit Trinket 5v + Neopixel Ring 12. I power each gate with a cheap USB power bank.Adafruit Trinket 5v 16MHz Mini Microcontroller I’ll likely end up combining the case and flange into one 3D printed part eventually. The case can be attached to a flange/foot with M3 screws, by marking and drilling a small hole in the flange. The shield attaches to the case with small M3 screws. I printed the case, lid, and two button pins. I plan to build more without the female headers, and will make a new lower profile case when I do.

I assembled the shield with female headers so the Trinket Pro could be removed, so the case is a bit bulky. I designed and 3D printed a case for the Trinket Pro. See this post for more details on building the gates:

I used the Trinket to hold the female headers correctly aligned while I soldered.

If so, push the wire through the hole, from the top towards the bottom, to ensure no wire is left exposed on top. The insulation on the wire may start to melt as the wire heats up. Melt a fair amount of solder on the wire and pad. With a small amount of solder on the tip of the iron, heat the wire right on the bottom of the pad.

If possible, use a vise to hold the PCB vertically, and a helping hands tool to hold the wires as they’re soldered.

I used a pre-assembled 3 pin JST-SM connector to connect the LEDs. Trim all the leads with a pair of wire cutters. I also built one of these DIY flexible soldering helping hands.įlip the board over and solder each leg of the resistor. I used this 3D printed vise to hold the PCB while soldering. If you’re new to soldering, I highly recommend reading through a good soldering tutorial, such as the ones by Adafruit and SparkFun. Note: Double-check the position, alignment, and orientation of each component very carefully before soldering! See this post for more details on building the gates: Code Parts that are not included, but are required to assemble:

ENIG (Electroless Nickel Immersion Gold) finish.

Purple SMOBC (solder mask over bare copper).

For larger quantities, power should be connected directly to the LEDs, and/or brightness should be limited in software. That’s enough for about 33 LEDs at max output (solid white, full brightness).

The large 5V trace and GND pour should be rated for up to 2 amps.

One digital output pin (D4) is run through a data line resistor, as recommended by Adafruit’s NeoPixel Best Practices. I made this shield because I was hand-wiring this same layout on perma-proto boards, which was time-consuming and unprofessional looking. No level shifter is required since the Trinket Pro 5V outputs the same 5 volt logic level that the LEDs require. The Adafruit Pro Trinket - 5V is an excellent Arduino compatible development board based on the ATmega328.

This is a shield/breakout for Adafruit Pro Trinket - 5V that makes it easy to control addressable RGB LEDs, such as WS2811, WS2812 (Adafruit NeoPixels), SK6812, etc. It takes a few weeks, and they require PCBs be ordered in multiples of three.
