Basically I want to hook up a few alligator clips to something like a plant and get some numbers back in my serial port...and then if I were to touch that plant I would get different numbers based on where and how I touch it. Then I could get a 0-1023 output and send that number off to another program. So for example - while the clips are hooked up I get some numbers in the 0-100 range...I touch the plant on one side, I get some other numbers from 300-600, I touch somewhere closer to the sensors, I get 800-100...etc.
So I see the arduino touche tutorial on instructibles...but I just want one number back and I'm really not sure how to get that out from that tutorial...it seems like only this weird graph thing is possible and I don't understand the code at all.
There is the capacitive touch sensor on SparkFun but that just seems to give you a yes or no if something is touched and not a varied number based on how you touch that thing...
so i was just wondering if anyone has any advice/guidance as to which direction to go or any info on touch sensing. are there any other methods I'm missing? is there an easy way to get a int variable so i could just do Serial.println(plantInfo); and get a 0-1023 number with either of the above methods? I'm looking for a quick and not necessarily super precise way of doing it...and a way that doesn't involve advance programming skills as mine are very basic.
Thanks so much for any help!!
