The following link gives schematics/information for a digital counter that has 3 decades (i.e. 0-999) and is constructed using 7-segment LED displays. A CD4553 BCD Counter in conjunction with a CD4511 BCD-to-7 segment driver forms the basis of the event/counter circuit (no microcontroller required).
