LAMP MATRIX CIRCUIT
The microprocessor sends a signal to the column circuit causing the output of the UNL-2803 to toggle.
When point "An drops low, the TIP1 07 transistor conducts and point "B" changes to a high state, At the same time,
the microprocessor drives the input of the 74LS74 low, causing a high at output 'F'. 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 10 a low, which is fed back to the 74LS74 and shuts the circuit off.
