I cut a lot of features, because there is no more space for me to burn the firmware into the board(32U4).
Now you can check your time and calendar there, a stopwatch is included too~
A NOT-SO-USEFUL flashlight is also there, ignoring the brightness of OLED is not so good.
The original and reference one is: http://blog.zakkemble.co.uk/diy-digital-wristwatch/, Instead of writing the codes in avr-style, I adopt his avr workbench into a arduino solution, so every one can download the codes and upload hex to his own hardware easier!
Step 1: Functions
There is a beautiful animation when the seconds plus+ ^_^
- You can set up the current time~
- Enter "stop watch" mode and start timer!
- Sleep mode help to save battery power
- Calendar mode
- Flash light
Step 2: Materials & Tools
Step 3: Software
If you are familiar with Arduino, you can make a watch now! Please mod a better looking beyond my design!
Please download and report bugs to me .THX Zak for his initial work!
Step 4: Handwork
A wired jumper you should pay attention to. There are two times within RTC module, but only one of them will be shown on the back of board: INTB. The main logic is: RTC and button will sent INT to MCU, and OLED changes according to the interruption. So connect the INT to the RX on Xadow compatible interface.
To make it simple and wear more comfortable, I cut off a short segment of cowhide.
Just use a little clip, it's on your hand now!
Step 5: Later Plans
raise your hand, point to the girl you like. You got the distance between you and her!
OK, this is only an imagination, if you guys think it's a cool idea, I will make a real smart watch including BLE module, adding ID to make it cool & fun & geek.
