IoTT's video: 16 8 Channel DIY DCC Servo Relay Decoder Part 3 Video 19

In Videos and I showed how to build and program a 16 channel servo decoder and while servos in my opinion are the most elegant way to control turnouts and signals, I am aware that many folks use either single or dual coil switch machines or slow motion stall motors. So it is time to add support for those switch machine types as well.
