The microprocessor toggles the output of the 74LS374. When point "A"drops low. point
"Boo
is
high. A high at point
"BOO
causes a low at point
"Coo.
When point
"COO
is low the coil/flashlamp is
grounded through the TIP 102 transistor and turns On. When point
"N'
toggles high the
cotl/flashlamp turns Off.

The microprocessor toggles the output of the 74LS374. When point "A" is low. point "B" the
collector of the 2N540 1 transistor is high. Once point "B" is high. point "C" the collector of the
TIP102 transistor is low. When point "C" is low the flashlamp is grounded through the TIP102
transistor and turns On. When point "A"toggles high the circuit shuts Off.
