cool! I'm gonna build one into a watch using an attiny13, but i'll only put 1 button, that will put time on 12h00 when pressed. i was trying to figure how to tell time<br /> with only 6 I/O. had a programm running on my arduino that displayed hours, blinked all leds, displayed minutes, but with 6 I/O I missed a led to display all minutes.<br /> <br /> <br /> <br />
