@MrDominoThat circuit is not going to work. No clipping happenning. I just simmulated... a negative pulse at the analog pin... bye..bye Arduino chip... ]
Do you have any suggestions? What program are you using to simulate it?
I'm really really new to electronics so I really don't know what to do for this. I did some basic stuff back in undergrad but the extent of my work since then has really been limited to wiring up some turnkey NI DAQ systems, voltage dividers, and popping in voltage regulators to try and stabilize voltage sources.
