Re: Analog (not the webstats) Input

If the anometer just sends a blip every cycle (clock cycle?), then isn't it a digital signal? Could you use an RS-232 port to listen to this signal? Or if the signal level is not high enough (RS-232 is 10V), then could you build a simple amplifier circuit and add a MAX-232 chip and then use a serial port? Just a few ideas.

Hmm, all very interesting. The digital/blip signal would almost work but there's more to it. (there is layers of info that isn't just blips unfortunatly) I was using that as an example. I know about the voltage issues, I won't blow my circut as these are non powered devices, I'll have to get them power (different issue, I'll figure that much out) but I won't blow my board luckily. The max-232 chip is where I was originally starting. I have a friend who's pretty good with circut boards and soddering so. . .	[reply]
