CodeBug Project: Clock!

Posted by shabaz Top Member Oct 17, 2015
With its 5x5 LED matrix, a binary coded decimal (BCD) clock is easy to create.   BCD is pretty easy - each column represents a digit, with the individual LEDs equating to 1, 2, 4 and 8. If the first two LEDs in a column are lit then that means the digit is 3 (the sum of 1+2).   Here is a BCD example from wikipedia that represents the time 10:37 in BCD: With the codebug I decided to build a 12-hour clock and to use the center LED to indicate the seconds:   When powered up ...
As you've probably heard, element14 is sponsoring, and entertaining the epic-sized crowds, at Maker Faire Rome, 2015.   But this year we're sharing our stand with the dudes from codebug. Even Big CodeBug has made the journey from the UK to Italy, and made it in one piece ready to rock the LEDs and dance with the code. Tom is on hand, walking the makers through their introduction to the handy little powerhouse wearable. People have been lining up to take their first foray into the exciti ...

There is a microcontroller, a 5x5 array of red LEDs, a couple of push-buttons, the USB connector and six holes of which two can be used to power the CodeBug if you don't want to use the USB su ...
