Moises Status Report 3/22

I’ve been focusing on improving the accuracy and reliability of the capacitive touch grid. I identified that the issue was likely caused by the dielectric material I was using—packing tape—which was too thin and didn’t fully separate the rows and columns. This caused interference, leading to false inputs.
To address this, I tested several alternative dielectrics and found that cardstock provided a more reliable solution. Using two MPR121 ICs, I successfully achieved proper functionality with a 3×3 grid of rows and columns.
Next, I plan to scale up to a 9×9 grid. Once that’s complete, I will focus on processing the input data from the MPR121 ICs to enable selection of specific points on the grid.
