The processor loggles the output of the 74LS374 . When point ·A" is low, point "6" the collector of the
2N5401 transistor, is high. Once point "S" is high, poinl "C' the collector of Ihe TIP102 transistor is low.
When point 'C' is low, the flashlamp is grounded through the transistor and turns on. When point 'AM
toggles high, the circuit shuts oft.

The processor loggles the output of the 74LS374 . When point "A" is low, point "8' the collector of Ihe
2N5401 transistor, is high. A high at point 'B· causes a jow at point ·C·. When point
'e"
is low the coill
ilashlamp is grounded throU\jh the trans istor and turos on. When point "A" toggles high the eoi l/flashlamp
turns off.
