Pressing a button shorts one\nof row lines to one of column lines, allowing current to flow between them. A\nmicrocontroller can scan these lines for a button-pressed state. To do this,\nit follows steps below. 1.Microcontroller sets all column and row lines to\ninput. 2.Then, it picks a row and sets it HIGH. 3.After that, it checks column\nlines one at a time. 4.If column connection stays LOW, button on the row has\nnot been pressed. 5.If it goes HIGH, microcontroller knows which row was set\nHIGH, and which column was detected HIGH when checked. 6.Finally, it knows\nwhich button was pressed that corresponds to detected row \u0026amp; column.
