Note:
1. OUT1 will latch the output state during reset.
2. Many modern relays come with a flyback diode pre-installed internal to the relay itself. If the
relay has this diode, ensure the relay polarity is properly connected. If this diode is not internal,
it should be added externally. A common diode such as a 1N4004 will work in most circumstances.
