Iron Man Bow Tie

This is a code snippet for an Arduino project that displays a NeoPixel ring with a specific color, intended to represent Iron Man's Arc Reactor. The code is written in C++ and uses the Adafruit NeoPixel library. Here's a breakdown of the code: **Includes** The code includes the necessary libraries: `Adafruit_NeoPixel.h` for working with NeoPixels and `avr/power.h` for power management on AVR-based Arduinos (such as the Arduino Uno). **Definitions** The code defines several constants: * `PIN`: The pin number connected to the NeoPixel ring. In this case, it's set to 1. * `NUMPIXELS`: The number of pixels in the NeoPixel ring. For a standard NeoPixel ring, this is set to 1, but for a Neopixel Jewel (7 pixels), it's set to 7. **Setup** In the `setup()` function, the NeoPixel library is initialized by calling `pixels.begin()`. This sets up the communication between the Arduino and the NeoPixels. **Loop** The `loop()` function runs indefinitely. It contains a loop that iterates over each pixel in the NeoPixel ring (from 0 to `NUMPIXELS - 1`). For each pixel, the code: * Sets the pixel's color using `pixels.Color(30,30,35)`, which represents the Iron Man Arc Reactor color in RGB. * Shows the updated pixel color on the hardware using `pixels.show()`. * Delays for a period of time (500 milliseconds) using `delay(delayval)`. **Neopixel Jewel Code** The code for the Neopixel Jewel is identical to the NeoPixel ring code, except that it sets `NUMPIXELS` to 7 instead of 1. Note that this code assumes you have already connected your NeoPixels or Neopixel Jewel to an Arduino and have installed the necessary libraries.
