Brooke, You can make some digits blink by changing them to spaces every other time you write out the string to the LCD. Write the string out about 4 times per second, resulting in two blinks per second. It's a bit more work, but it gives better control of the display. -- --David Forbes, Tucson, AZ http://www.cathodecorner.com/ _______________________________________________ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
