Arduino Smart Watch

A very basic yet expandable smart watch based upon Adafruit's 5v Pro Trinket board

Similar projects worth following
My "Arduino smart watch" project is a simple yet very capable Arduino based platform. The current version of the watch is functioning correctly and is at a size that I could confidently wear (1.4cm in width).
The current version is based upon adafruit's pro trinket board (5v) which is both a great size and capable of running my program. The watch is powered by a 500mah lipo batter (located on the wrist band as to remove thickness) and the voltage is boosted using Adafruit's basic 500 power boost. The program is very basic at the moment (i am hoping to add temperature and possibly connectivity with my phone in the future) and only projects time, AM and PM and what time my next period begins (based off my school time-table).
The case was printed using PLA plastic on my Printbot simple metal and designed in 123d Autodesk design. The main feature of the watch is its ability to be programmable and its ability to expand and act as a useful and reliable platform.

Libraries used:

FTOLED (Oled screen driver)

  • 1 × Freetronics 128X128 OLED screen
  • 1 × Adafruit 500mah Lipo
  • 1 × Adafruit 5v pro trinket Arduino board
  • 1 × Adafruit Basic 500 5V power boost

    After putting this project away for some time (to make room for another project soon to be released on my profile) I have decided to rebuild/resolder the whole watch. The 3D printed case and band will stay put however the circuitry will be re soldered and cleaned out. The reasons behind this is due to my lazy and terrible wiring (as per the images) and because if I am going to be wearing the watch I want it to be 100% safe and functional (Don't want any short circuits while I'm wearing it at school). I also believe that rebuilding the watch will increase its longevity. I have decided not to create a custom PCB due to time/money and I don't want the waste the components I currently have. I will also be creating a more sophisticated GUI for the watch since it's current version is very basic (which isnt always a bad thing...). Stay tuned for more on the watch, and check out my profile in the upcoming weeks for a new project (Star Wars themed) :)

  • Buttons and wires....

    The much needed push buttons are now installed, meaning I can now change the time without having to change the code. The new buttons will also be helpful for my new UI. I am hoping to create a user interface with a menu (much like typical smart watches) instead of just the basic time and event updater.

    And of-course with every project the wires are a pain... Next time i make a watch I'm going straight to Eagle PCB creator...

    Here is a photo of the inside view of the watch. The Pro trinket is located on the upper end, and the power boost is on the lower end. Due to the fact that my watch is not made using a custom circuit board and utilizes only "Off the shelf components" there is not much room for expansion. I hope to install my TMP36 temperature sensor in the near future and make some software changes. Sorry for the inactivity, stay tuned for more updates in the upcoming weeks

bluetooth or WiFi?

  Are you sure? yes | no

Austin Marandos wrote 11/23/2015 at 10:03 point

none at the moment, I will hopefully be adding bluetooth in the future

  Are you sure? yes | no

Great! How much time does the battery last?

  Are you sure? yes | no

Austin Marandos wrote 09/21/2015 at 07:55 point

Hey Ben, I haven't tested it for that long to know, I will let you know once I have worn it for long enough! :) . I believe however that theoretically it should last around 7-9 hours.

  Are you sure? yes | no
