Wearable Wayfinder
The Wearable Wayfinder is a totally programmable, beautiful little computer for your wrist packed with sensors.
The Wearable Wayfinder is a DIY programmable smart watch packed with sensors. Totally open and hackable this little gadget can do so much! Play and program fun gesture-based games, track your daily physical activity, display beautiful digital watch faces and compasses.
Check them out in our store
! Totally portable this device comes with a rechargeable lithium battery. USB ready out of the box, the Wayfinder can be programmed as a keyboard or a mouse to interface with virtually any laptop or desktop computer. It is Arduino compatible so you can program it with the popular Arduino Platform. Just follow the step-by-step instructions below. It comes with a real time clock, a compass, accelerometer, and temperature sensor, as well as a glorious
TFT LCD screen
with tens of thousands of colors right there on your wrist! We have crafted a 3D printed enclosure with space for the battery and a standard watch band.
This widget is LUCID-- You can take it apart an re-assemble it to your heart's content. The PCB is intricately silkscreened and labelled so you will learn as you play. The board also includes a thumb wheel potentiometer, two buttons, two LEDs and a power switch. We think the Wearable Wayfinder is an excellent platform for learning C++ programming because it is simple to use, yet incredibly powerful. The Wayfinder can connect with other devices using the I2C or serial protocols, or by using any of the four GPIO pins or two analog inputs.
We have written tons of programs for the Wayfinder which you can peruse and hack to you heart's content! For example check out our color clock , cellular automata animation , color compass , and alarm clock ! And let us know about your next project in the comments!

Wearable Wayfinder Video
The Wearable Wayfinder displyaing its awesome capabilities.
The Wearable Wayfinder Diagnostic Code in Action
This video shows the Wearable Wayfinder running the Wearable Wayfinder Diagnostic sketch which you can find below. Nothing too exciting but you should run this code to see that all the sensors are working. Left button triggers the piezo speaker, the other changes the color.
Wearable Wayfinder Diagnostic Arduino Code
This code shows the output from all the Wearable Wayfinder's sensors. The buttons trigger the piezo speaker and changing the text color. While it isn't to exciting this code serves as a nice stub for any project you may want to do with the Wearable Wayfinder. It is a good idea to make sure this code runs correctly before diving all the way into the awesome world of the Wayfinder :)!

Adafruit Graphics Library
The Adafruit GFX library. This is the wonderful work of adafruit we just host it here for convenience. We made the most minor modification of replacing the dash in the library folder with an underscore so this baby is ready for your Arduino library folder out of the box :) Check out the
GitHub page
for the latest.

MMA8453Q Accelerometer Arduino Library
Download the MMA8453Q Accelerometer library from Github!
Learn more about this library at our
tutorial!
.
I2C Arduino Library
Similar to the wire library but more flexible. You may wonder why we cannot use the standard Arduino Wire library, it is because the MMA8453Q uses a repeated start condition for the read operations and the default Wire library cannot handle those without modification.
