The Microprocessor toggles the output of the 74LS374. When point "A" is low, point "B" the collector of
the 2N5401 transistor is high. Once point "B" is high, point "C" the collector of the TIPI02 transistor is
low. When Point "C" is low the flashlamp is grounded through the transistor and the flashlamp turns On.
When point "A" toggles high the circuit shuts Off.
