# NeoTrellis Game ## Overview https://youtu.be/ytr_AzqjuaE ## Project Overview The NeoTrellis is controlled by the Adafruit Feather M0 Express via Circuit Python. An LED push button acts as an input. Toggle switch for powering the circuit on and off. This basic set of parts is all we need to build a little game project. This uses slightly modified demo code from the NeoTrellis guide. Special thanks to [John Park](https://learn.adafruit.com/users/johnpark) and [Kirby Griese Jr](https://learn.adafruit.com/users/Keebie81).  ![3d_printing_hero-parts-2.jpg](https://cdn-learn.adafruit.com/assets/assets/000/063/239/medium640/3d_printing_hero-parts-2.jpg?1539044655) ## DIY NeoTrellis Game Color matching games are fun and easy to play. This project plays on the basic concept and makes use of the full color NeoPixel LEDs. On start, a single pixel will light up in a random color. Press all of the buttons and try to match the first color. Random colors will be triggered the more you press buttons. Match all buttons to the first color to win! Press and hold the push button to reset.  ![3d_printing_hero-neotrellis.jpg](https://cdn-learn.adafruit.com/assets/assets/000/063/137/medium640/3d_printing_hero-neotrellis.jpg?1538925704) Using the Adafruit Feather M0 Express, we employ a 1200mAh lithium polymer battery to make this portable – Recharge the battery over USB. An LED metal push button is used to reset the game. A mini toggle switch is used to power on the game on and off. All of the electronics are housed in a snap fit 3D printed case.  ![](https://cdn-learn.adafruit.com/assets/assets/000/063/071/medium800/3d_printing_parts.jpg?1538747349) ## Parts List Components used to build this project. - [Adafruit NeoTrellis 4x4 Button PCB](https://www.adafruit.com/product/3954) - [Silicone Elastomer 4x4 Button Keypad](https://www.adafruit.com/product/1611) - [Adafruit Feather M0 Express](https://www.adafruit.com/product/3403) - [1200mAh lipo battery](https://www.adafruit.com/product/258) - [16mm panel mount button](https://www.adafruit.com/product/1445) - (optional upgrade) [16mm Metal Push button](https://www.adafruit.com/product/559) - [Mini Toggle Switch](https://www.adafruit.com/product/3221) ## Hardware + Supplies Wires, connectors, and hardware screws. - [Silicone cover stranded-core ribble cable](https://www.adafruit.com/product/3890) - [Male and Female JST Connectors](http://a.co/d/cpAMuPw) - [Heat Shrink Tubing](https://www.adafruit.com/product/1649) - 4x [M2.5 x 5mm metric machine screws](https://www.albanycountyfasteners.com/2-5-MM-x-45-Phillips-Flat-Head-Machine-Screw-p/1011-1002.htm) ## Tools List of handy things to assist in any project. - [Wire Strippers](https://www.adafruit.com/product/527) - [Wire Cutters](https://www.adafruit.com/product/152) - [Soldering Iron](https://www.adafruit.com/product/180) - [Solder Wire](https://www.adafruit.com/product/734) - [Panavise Jr.](https://www.adafruit.com/product/151) - [Third Helping Hands](https://www.adafruit.com/product/291) - [Monoprice Inventor II](https://www.adafruit.com/product/3897) ## Prerequisite Guides If you're new to Adafruit Feather M0 Express, CircuitPython or soldering, take a moment to walk through the following guides to get you started. - [Adafruit Feather M0 Express Intro](https://learn.adafruit.com/adafruit-feather-m0-express-designed-for-circuit-python-circuitpython) - [Adafruit NeoTrellis Intro](https://learn.adafruit.com/adafruit-neotrellis) - [Welcome to Circuit Python](https://learn.adafruit.com/welcome-to-circuitpython) - [Adafruit's Guide to Excellent Soldering](https://learn.adafruit.com/adafruit-guide-excellent-soldering?view=all) - [Next Page](https://learn.adafruit.com/neotrellis-box-game/circuit-diagram.md) ## Featured Products ### Adafruit NeoTrellis RGB Driver PCB for 4x4 Keypad [Adafruit NeoTrellis RGB Driver PCB for 4x4 Keypad](https://www.adafruit.com/product/3954) By popular request, we've upgraded our popular Trellis elastomer button kits to now have a PCB with _full color NeoPixel_ support!
