The microprocessor sends a Signal to the column circuit causing the output of the UNL-2803 to toggle.
When point "A" drops low, the TIP107 transistor conducts and point "8" changes to a high state. At the
same time, the microprocessor drives the input of the 74LS74 low, causing a high at output
"P'.
A high
state at the base of the TIP102 causes the transistor to conducts, bringing the row circuit to ground and
turning the lamp on. The microprocessor changes the input of the 74LS74 to a high state to turn the lamp
off. In overcurrent conditions, the lamp is shut off through the comparator. If the voltage at the negative
input of the LM339 rises above 1.4V, the output changes to a low, which is fed back to the 74LS74 and
shuts the circuit off.
