Hi to all,
I have started by asking the simplest question.
How do I get these or similar items (shields and phidgets) to work just by them selves?
Going to start first with the pH Phidget 1130.
(Because it is the most important to me.)
So first thing. Phidgets are a little different in the way they report data back to the device.
I originally found good info about this here Phidgets and Arduino - Sensors - Arduino Forum
ill give a thanks to that user. (mapiram)
you will need the above info so look at it. I'm not gonna re write it because looking for information will strengthen your understanding in the end. so even though I have given you the place to look you still have to put a little effort in to get and understand the info.
your welcome.
Please make sure you understand how to utilize the Arduino before attempting a project. I like www.udemy.com courses but there are plenty of free resources out there. But remember when you pay for something you can expect support.
If you don't understand the other post ask and ill address your issue.
So back to the Phidgets pH 1130 and interfacing to your Arduino.
I stated by grabbing a set of jumper wires.
Red = 5v
Black = GND
White = Read (this will go on my A0 pin on my Mega)
I hooked my device through a bread board. When looking at the pics to ignore the wires I don't mention.
