I'm completely new to Arduino. I'm tasked by my boss to set up a previous behavioral assay without a protocol (last person didn't leave one). We used Arduino to detect resistance change (I think), then send a TTL as an output.
The set up looks like this. I assume when the mouse licks the bottle, it'd change the resistance.
The question is, how could I proceed with the code to detect the resistance change? I'm also confused as for whether I need to hook up a battery.
Please excuse my poor explanations. Please ask any questions!!!!! I really appreciate it.
