SWITCH MATRIX CIRCUIT
The microprocessor is constantly strobing the column side of the switch. When point "N on the column circuit toggles low, the
column side is active.
When a switch closes, the row side of the circuit activates, The "+" input to the LM339 drops below +5V causing its output to go
low. Corresponding row and column switches must be low at the same time for the switch to be considered closed by the
microprocessor. When the switch opens, the "+" input to the LM339 is above +5V, its output is high and the row is inactive.
