ADAFRUIT TRINKET TUTORIAL INSTALL
ADAFRUIT TRINKET TUTORIAL CODE

Once the environment is installed, start a new project, copy the code at the end of this page, select the board type, the port and upload the program. Tip: If you plan on using a non-Arduino-branded board (like the Adafruit Trinket M0 in this project), it is easier to follow the manufacturer's instructions, for example t he Adafruit Arduino IDE setup page, as they include setting up the environment with the corresponding boards and libraries. If you don't already have an Arduino environment installed, this is the time to do it. Depending on the buttons used, this can mean that either the buttons have to be tested unsoldered, or they have to be desoldered and resoldered after installation inside the case. Tip: Always test the code and wiring before starting to put the electronics inside the enclosure. If you use buttons as shown in this project that are screwed from the bottom, make sure you solder the buttons after they are in place in their respective holes. That makes it easier to attach the wires to the legs and greatly simplifies soldering. Most buttons have small holes in their legs. I suggest soldering the wires to the Trinket from the top (as shown on the picture below) so that there is no clearance issue at the bottom. The connections are shown on the fritzing diagram at the bottom of this page. There are just 7 solder joints to make on this project. Tip: I recommend using solid core wires for this project as they are easier to solder and work with and they will not be exposed to repeated flexing. The enclosure will need to have a hole cut to insert the USB plug. The Trinket must be very solidly mounted to the enclosure to sustain the high stress of USB cable insertion. Do not buy buttons that need to be soldered to a board.

Buttons should attach to the enclosure.

Here are some parameters worth considering when picking an enclosure and buttons: I added the references in the hardware list, but these are by no means the only or best options. I just went to my local electronic store and bought some I liked. There is a wide choice of enclosures and buttons to do this project. The SAMD21 inside the new Trinket M0 has USB keyboard and mouse capability in hardware and it has shown to be perfectly reliable. The original Trinket is ATtiny85-based and that chip does not have native USB keyboard capable hardware, so the project uses a bit-banged (i.e. This worked, but not completely reliably, especially behind some USB hubs. I had originally made this project with the older Adafruit Trinket 5V using the Adafruit Trinket USB Keyboard instructions. I like the Trinket M0 because it is really small (and this project only needs a small number of I/Os, so no need for the bigger boards) and it is inexpensive ($8.95). It can be replaced by pretty much any of the other Atmel ATSAMD21-based boards like the Arduino MKR ZERO or the SparkFun SAMD21 Mini Breakout.

The key component for this project is the Adafruit Trinket M0.

It saves me from having to reach for the keyboard or remembering keyboard shortcuts. Please note! They look great, but we don't recommend putting the goggles over your eyes when they're all lit up since the lights can be bright and the goggle lenses can be hard to see out of.This is a very simple, yet useful introductory project to Arduino, USB and buttons. You'll also need a classic USB Micro B cable to program the Trinket, we don't include it as people tend to have too many USB cables in their desk drawer, but if you need one, you can get it from us here. The soldering is easy and is possible to do by beginners, its a 1-2 hour project (30 minutes if you are a kit-making expert!) Check the tutorial page to see what you'll need to complete the project! We don't include a soldering iron or solder but sell them in the Adafruit store and you can find epoxy or hot glue at most hardware/craft stores.

You'll need some basic soldering and hand tools to install the JST connector on the bottom side of the Trinket and connect your NeoPixel rings. These are fairly easy to put together and should take around an hour to make. The LED rings fit perfectly inside 50mm round goggles and we include a 3.7v 150mAh battery and and Micro Lipo charger so you can run the battery and charge it all while contained in the goggles themselves. The pack contains almost everything you need to put a pair of NeoPixel Rings in our costume goggles and power them with an Adafruit Trinket.

It's a great easy build and when you're done you'll have the coolest accessory.ДЇollow along with our popular Kaleidoscope Eyes tutorial. It even comes with a rechargeable LiPoly battery and charger. One of the most popular Trinket projects now has its own kit pack! Make your very own programmable NeoPixel goggles with 2 x 16 LED rings and an Adafruit Trinket. As of October 12th, 2015 this product now ships with an Adafruit Trinket with a micro-USB plug.
