# NeoPixel Jack-o-lantern ## Overview ![](https://cdn-learn.adafruit.com/assets/assets/000/028/341/medium800thumb/led_pixels_Kdl8LZ.jpg?1448323852) When unpacking an inexpensive plastic Jack-o-lantern for this year's Halloween decorating, I got inspired to upgrade it with some NeoPixels. This project only uses a few parts: - [NeoPixel Ring](http://www.adafruit.com/products/1463) (16 or 12 pixels) - [Arduino Uno](http://www.adafruit.com/products/50) (or compatible like the [Adafruit Metro](http://www.adafruit.com/products/2488)) - Few inches of 20 AWG wire - [9v power supply](http://www.adafruit.com/products/63) (optional) - One 470 ohm resistor (optional) - 2-1/2" square of shiny mylar and clear tape (optional) ![](https://cdn-learn.adafruit.com/assets/assets/000/028/330/medium800/led_pixels_15_-_1.jpg?1446129626) For tools, you will need: - Soldering Iron - Wire stripper - Diagonal cutter (For trimming soldered wires) Let's light up a pumpkin! - [Next Page](https://learn.adafruit.com/neopixel-jack-o-lantern/power.md) ## Featured Products ### NeoPixel Ring - 16 x 5050 RGB LED with Integrated Drivers [NeoPixel Ring - 16 x 5050 RGB LED with Integrated Drivers](https://www.adafruit.com/product/1463) Round and round and round they go! 16 ultra bright smart LED NeoPixels are arranged in a circle with 1.75" (44.5mm) outer diameter. The rings are 'chainable' - connect the output pin of one to the input pin of another. Use only one microcontroller pin to control as many as you can...

The processor has plenty of GPIO, Analog inputs, hardware UART SPI and I2C, timers and PWM galore - just enough for most simple projects. When we need to go small, we use a No Longer Stocked [Buy Now](https://www.adafruit.com/product/2480) [Related Guides to the Product](https://learn.adafruit.com/products/2480/guides) ### 9 VDC 1000mA regulated switching power adapter - UL listed [9 VDC 1000mA regulated switching power adapter - UL listed](https://www.adafruit.com/product/63) This is a really nice power supply. It's a switching DC supply so it's small and light and efficient. It is thin so it fits in power strips without blocking other outlets. The output is regulated so you'll get a steady 9V up to 1000mA (1 Amp) of current draw. 5.5mm/2.1mm barrel...
