Hello everybody!
First of all, I would like to thank everyone that is taking the time to read this!
I am in the middle of my thesis project from university, which consists on adapting and optimating obstetrical forceps. On the surface of the forceps a pressure sensor matrix mat will be attached, to be able to get a pressure feedback from the pressure the doctor is applying on the babys head. (very very much summarized).
For the data acquisition and data processing I have found a tutorial from the company Sensitronics. They explain and give the code to read a matrix sensor of 16x10 with an Arduino Uno.
My sensor consists of 7x5 electrodes instead of 16x10 and I am trying to adapt the code that I have to my sensor.
Could anybody help me out? I am a little bit lost in the subject.
On the Zip folder attached, I have provided the Circuit and the Sensor layout, for both my sensor and the one I have as exaple (so you guys can see easier for yourselfs what the situation is), as well as the Arduino Code that I am trying to adapt.
My circuit consist of one less multiplexer and one less shiftregister, as the one I have as an example. And on the code I cant really recognize where the programming for these components is.
I would be so thankful if someobody could help me out with this.
Have a very nice day
