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 "S" causes point
"e"
the collector of the TIP102 transistor, and point "D" the emitter of
the TIP36 transistor to drop low. When point
"0"
is low the coil is grounded through the transistor and the coil 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 "S" the collector of the 2N5401
transistor is driven high. A high at point "S" tums On the TIP102 transistor and causes point "C" to drop low. When
point
"CO
is low the coil is grounded through the transistor and the coil turns On. The coil shuts Off when point
"AO
toggles high.
