Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Hi All

I thought I would share my Saturday afternoon creation
Nothing spectacular just a Binary clock using I2C and 2 PCF8574 expanders
Could have just used the Maximite's I/O pins but I like the idea of a little
add on board with just 4 wires.
Left columns are hours (Tens - Units). Right is the minutes (Tens - Units)
Amber LED in middle flash's at 1 second intervals
The time shown is 10:05



Source code attached (rough and ready but it works)


Regards
