Hey all,
I have been trying to piece together a track timer for my local cub scout troop's pinewood derby (racing small wooden cars down an incline), and I would like the finish line to have two separate timers displaying the finish time of each lane. As I have it set up right now, I need my controller to send a signal of a particular frequency to a "display" circuit which will show the current race time down to milliseconds. Big question is, how can I run both of these timers simultaneously and still be able to stop one lane's timer while having the other continue? Thanks in advance!
