Problem
A 16x16 resistive pressure matrix needed clean readings from all 256 elements. [Add: application and accuracy needed.]
Hardware
A custom signal-conditioning PCB designed in EAGLE and checked in Proteus. [Add: multiplexing scheme, amplifier stage, layout choices.]
Firmware
C/C++ on an Arduino UNO scanning the matrix, with LabVIEW on the PC side. [Add: scan rate, calibration.]
Result
A signal-conditioning PCB and acquisition system for the 256-element sensor. [Add: scan rate, resolution, noise measured.]
