Hi all,
I'm a bit of a beginner at electronics, but have taught myself quite a lot over the last year or so.
I recently bought a PH meter on ebay, and have soldered the wires out of it and into a breadboard. I have put my multimeter across the two points in the breadboard and I get the reading on the meter.
I also have a usb Velleman card with two analog inputs.
I'd like to be able to read the input into the card so I can report the PH level of soil to my PC. The PC part and the card reading I can do, it's getting the signal to the card I am stuck with.
Can anyone point me in the right direction?
