I don't have anything yet, except what I want my program to successfully do. After thought a 3 segment LED display will be enough for my counting since I only want it to go to the hundreths place 0-999.
7-Segment LEDs sound like they would work just fine in this project, but you'll have to consider how big you want them. The more common ones are around 1 inch in height. Those tend to require very little external components to drive them. Depending on the environment,though, that might not be big enough.
I do not have a RTC module yet. Any suggestions?
How accurate do you want it to be? Is a couple seconds a day OK? If so, I would recommend something like the DS1307 kit that adafruit sells for about $10. If you want poinpoint accuracy, you could invest in a WiFi/Ethernet shield and update using NTP.
