I was curious if something like this will work!
+ shared to two arduinos
- to one arduino, and grounds connected to the arduinos together.
Then I can have a 10k resister on the + of the thermister at each side and have no differences in reading at each side?
10K Thermister has one side of Analog Input 1 from two arduinos connected (A1 from Arduino 1, A1 from Arduino 2). The other side goes to ground on one of the arduinos, and both arduinos have the grounds connected together.
Would the measurement of temperature at each one then be identical?
What I want to do is similar, I'm just curious if something like that would work? The reason I ask is I gather a thermister connection requires readings from the mid point of a 10k circuit (i.e. thermister on one side, 10k resister on the other, temperature reading is at the mid point of that).
It was suggested to use UnityGain Amplifier - not sure how that works for it's input?http://www.electronics-tutorials.ws/opamp/opamp_5.html
Whilst looking in to op amps, I came across this page, now will I be able to take the Positive side of the thermister and use some sort of following circuit to SHARE the input with both controllers?
