Using timers and counters.

Projects General Guidance
1

I've got a project where I want to count a signal from a shock sensor for 5 seconds.

Push the button
delays 3 seconds
Outputs a buzzer
starts 5 second timer
counts number of inputs from sensor
buzzes again at 5 seconds
outputs number of hits to lcd.

I don't expect anyone to do it for me but I'd sure appreciate it if someone would point me in the right direction.

Thanks guys

Lots of ways to implement a counter:
int i = 0;
i = i + 1; // Increase counter by 1
i += 1; // Increase counter by 1
i++; // Increase counter by 1

For a timer:
unsigned long startTime = millis();

if (millis() - startTime > 5000) // 5-second timer has expired
{
}

Thanks,

Would you know of any project on-line that uses this method that I could modify for my use?

Well, the BlinkWithoutDelay example (File->Examples->2.Digital->BlinkWithoutDelay) would be a good place to start.
