Since our system only needs to detect one input at a time, rather than handling multiple simultaneous touches, I realized we could allow for slightly more spacing between the capacitors without sacrificing functionality.<\/p>\n<p>Based on this, I designed a 12in x 12in grid using 1-inch-wide copper foil strips, with 0.375-inch (3\/8-inch) gaps between each strip. This layout results in 1-inch by 1-inch capacitor squares, separated by 0.375-inch gaps.<\/p>\n<p>Additionally, I plan to test different dielectric materials to determine which works best, including parchment paper and packing tape.<\/p>\n<p>I do feel slightly behind schedule, as I had hoped to have the board built and begin testing with the MPR121 sensors by now. However, since the sensors have not yet arrived,\u00a0 and I had a fairly busy week with multiple projects, exams and assignments I fell behind.<\/p>\n<p>Therefore my next steps will be to:<\/p>\n<ul>\n<li>Start writing pseudocode for the Raspberry Pi to prepare for debugging.<\/li>\n<li>Build a test grid to begin preliminary experiments as soon as the sensors arrive.<\/li>\n<li>If the MPR121 arrive, do testing as soon as possible and possibly begin working on implementing the full 9&#215;9 grid.<img decoding=\"async\" loading=\"lazy\" class=\"alignnone size-medium wp-image-151\" src=\"http:\/\/course.ece.cmu.edu\/~ece500\/projects\/s25-teamf3\/wp-content\/uploads\/sites\/378\/2025\/02\/Grid-300x278.png\" alt=\"\" width=\"300\" height=\"278\" srcset=\"http:\/\/course.ece.cmu.edu\/~ece500\/projects\/s25-teamf3\/wp-content\/uploads\/sites\/378\/2025\/02\/Grid-300x278.png 300w, http:\/\/course.ece.cmu.edu\/~ece500\/projects\/s25-teamf3\/wp-content\/uploads\/sites\/378\/2025\/02\/Grid.png 755w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>This week, I focused on determining the appropriate sizing for the capacitive touch grid, including the spacing required for a 9 x 9 grid system.
