Hello,
I'm looking for help building a score board timer for a prototype hockey game I'm working on.
What I need,
OK, I need a clock for the score board, that, simply put, will start at a pre-determined time say 5 min. then count down to 0.
when the clock hits 0 it needs to turn on a light and keep it lit, then reset to 5min, count down to 0 again
light a second light, then count down one final time to 0, signal a sound and a light and stop.
then have the ability to reset and start the whole process over again.
would like the ability to choose how long each period is, if at all possible.... as 5 might be to long.
recap:
Start button
count down from 5 *signal light*
count down from 5 *signal light*
count down from 5 *signal light AND horn/sound*
Reset
if any one can help me I would love ANY help finding out what parts I would need.
thanks!
