Can you help me expand this idea a bit? I want to build a punch counter for my son's martial arts club. It will count the number of hits to a punching board (bag) in 45 seconds.

Ideally, what I envision is a reset button, triggering a set of warning beeps......

beep, beep, beeeeeeeeeeeeeep, a small counting display 1-45 seconds and a much larger display for the count (3 digits would suffice) followed by a long beep and stop and freeze the count until the next reset.

Although it might be possible to trigger it with a switch, I think an accelerometer might be the way to go.

I have all the parts to build, but I am a complete beginner on the programming side and I could use some help. I want to learn this stuff, but I need this project sooner than later. ;-)

Any offers to help greatly appreciated!

Best Regards, Dennis

How would you edit this to make it count down as well
