Here I have basic LED multiplex IC (HT16K33). I want to add different resistors in my multiplex circuit and measure them at each x,y position with my ADC IC (ADS1115).
For some reason it won't register any measurements (values oscillate in sine as usual when nothing is attached). I tried with adding another transistor, but without changes. I'm really new in this, so any help appreciated. Is this possible at all, or I have to try different approach?
PS. These IC's are as complete modules with all the resistors and capacitors they need to function, I didn't bother to draw them.
