Quick Start Guide

Get your NeoRing running with a rainbow effect in under 5 minutes.

Prerequisites

  • Arduino IDE (1.8+) or Arduino IDE 2.x
  • An Arduino-compatible board (Uno, Nano, ESP32, RP2040, etc.)
  • A USB cable
  • 3 jumper wires

Step 1: Install the Library

  1. Open Arduino IDE
  2. Go to Sketch → Include Library → Manage Libraries
  3. Search for "RobotechPixel"
  4. Click Install (this also installs the Adafruit NeoPixel dependency)

Step 2: Wire the NeoRing

Connect 3 wires from your board to the NeoRing:

NeoRing PinArduino PinDescription
5V5VPower supply
GNDGNDGround
DINPin 7Data input (default)

Note: At full brightness with all LEDs white, the NeoRing draws up to 0.68A (measured). A single board is USB-safe even at full brightness on USB-C (1.5A) or USB 3.x (900mA) ports. USB 2.0 (500mA) is marginal at full brightness — reduce brightness or use an external supply. The default firmware limits brightness to 150/255 as a conservative default for multi-board setups.

Step 3: Upload Your First Sketch

#include <RobotechPixel.h>

RobotechPixel px(BOARD_NEORING, 1, 7);

void setup() { px.begin(); }

void loop() {
  fxRainbowWheel(px, millis());
  px.show();
}

Upload this sketch to your board. You should see a rainbow spinning around both rings!

Step 4: Try More Effects

Replace fxRainbowWheel with any of the 26 built-in effects:

// Fire simulation
fxFireRing(px, millis());

// Comet trails
fxComets(px, millis());

// Dual spinning rings
fxDualSpin(px, millis());

// Breathing pulse
fxBreathing(px, millis());

See the full Effects Reference for all available effects and their parameters.
