The processor toggles the output of
the
74lS314 .
When point -A" is low, point '8~ the collector of the
2N5401 transistor, is high. A high at polnt 'S' causes point 'C', the collector of the TIP102 transistor, and
point ·0\ the emitter of the TIP36C transistor, to drop low.. When point '0· is low, the coil is
grou!'ll1ed
through the transistor
and
turns on. The coil shuts off when point ·A· toggles high.
