I was trying to figure out the flex sensor and how to get a flex input from it. This was the result of wiring things up according to the previously mentioned Sparkfun tutorial. Somehow even though I was bending the sensor, the reading came back static.
Brought up this issue with David in the tutorial earlier today, and he quickly realised it was a simple wiring issue - the connections to the breadboard were not stable. After switching the positions of the jumper cables we got it to generate the readings I needed.
Since both my primary inputs were sorted, and buttons shouldn't have any issues, we discussed that my next steps should be to make a prototype in Arduino that could get these readings from the Arduino.
I mentioned in the previous blog post that I'd quickly explain once again what I'm trying to do.

Basically, as you can see from this very meticulous and detailed sketch, the MPU-9250 sensor's purpose is to detect when the heart is lifted up, so that it can initiate the whole interaction. I want to place the flex sensor close to the surface of the silicone heart, so that when it is compressed the sensor detects the degree to which it is pressed down, and can respond accordingly.
After talking to David, I've moved away from the suspended mannequin design in my initial proposal, need to confirm this with Ian. This is partially due to the fact that my silicone heart will have a flat back instead of being completely 3D, as well as logistical hurdles or hanging it up. I've yet to decide how exactly I'm gonna mount the heart, and how users can lift it up, but sorting out prototyping stuff for now.
