We make the rows as i/p and we drive the columns making them o/p, this entire procedure of reading the keyboard is named scanning. A three x 4 matrix keypad is used for information entry. Interrupt Service Routine has not been used in the program. The three columns of the keypad are connected to 3 of the output signals from the PIC. The four rows of the keypad are related to four of the enter indicators to the PIC. If no key is pressed there isn't any electrical contact between the rows and the columns. The PIC detects which key is pressed by ‘scanning’ the keypad. First the PIC makes the column 1 current column and sets the signal going to Col- umn 1 low (a digital ‘0’). All the other Columns are made high (a digital ‘1’). Then it assessments the enter signals
coming from each Row in flip. If any of the Row indicators is low, this means that the corresponding key in Column 1 has been pressed. Interrupt Service Routine has not been used in this system.
