The microprocessor toggles the output of the 74LS374. When point "A" drops low, point "8" the
collector of the 2N5401 transistor is high. A high at point "8" causes point "C" the collector of the
TIP102 transistor, and point "0" the emitter of the transistor to drop low. When point "0" is low
the coil is grounded through the transistor and turns On. The coil shuts Off when point "A"
'._ toggles high.

The microprocessor toggles the output of the 74LS374. When point "A" is low, point "8" the
collector of the 2N5401 transistor is driver high. A high at point "8" turns On the TIP102 transistor
and causes point "C" to drop low. When point "C" is low the coil is grounded through the
transistor and turns On. The coil shuts Off when point "A" toggles high.
