Simple Counter/Timer Circuit?

I am a newbie interested in building a circuit that can count the number of times a voltage level exceeds 2 volts. Long story but I have an EMG device that will output 2 volts once a threshold is exceeded. There is no way to automatically capture the number of times this happens. Can anyone point me to a project kit that I could purchase or to a circuit with a component list that I could build? I am fairly new so hopefully this circuit would not be too complex. While not critical if it is also possible to capture the average duration the level stayed above 2 volts that would be great. Understanding that this may complicate things beyond my ability the simple counter without duration would suffice. Thanks.

you should design a simple comparator ... stet its thershold voltages less then or equal to 2. So that when ever there is a voltage level of 2V the comparator will give the output of 5 volts.... and with that 5 volt you can attach a simple counter circuit... to count it....

You could use the PICAXE family of microcontrollers for this. If you google PICAXE, you can find various websites that sell complete kits, like this one http://www.picaxe.com/

To program a counter is failry simple, maybe 10 lines of code.Its fairly simple to program and use, and if you need help with the code, let me know and I can help you with that as well.

You will need to download the PICAXE programming editor ( For windows based OS) on your laptop / PC / system. This is the software that you use to program the chip.

The input range of voltages are fairly low, so it can directly detect 2 Volts and produce an output.

Hope this helps, and if you end up going the picaxe way and need help with coding, let me know.
