Nice video - did you consider interfacing the strain gauge via a Wheatstone bridge for improved accuracy?

Hey would mind doing a video on how to control a servo with a joystick wirelessly through bluetooth?

For higher resolution, could you use a lower voltage reference? Instead of 12 bits across 3.3v, you could set it to 12 bits across 1.1v see an improvement, right?

have you tested the response time for these kinds of system? I'm looking for a sensor that can detect rubber ammunition impact but the time of contact is too small for a typical arduino pressure sensor...So I was wondering if this is sensitive enough for a sudden pressure change, Thanks!

Hmm, I never heard of the "plotter" before. I'll have to look into that. Thumbs up...PEACE

I'm gonna use this idea to weigh my wife.  She won't tell me what she weighs.

Is the output graph strain or force? Please answer?!?!
