You can set the DCC address, the swing range in degrees and whether the servo is 'inverted' i.e.

The servos now need to be set up through commands issued to the serial interface. This is a heartbeat indicator that lets you know the unit is alive. Once loaded, you should see the on-board led flash once per second. This makes use of the NRMA dcc decoder library and also the servo controller library. NOTE: because we are powering the unit from DCC track power, there is no need to opto isolate the data feed into the Nano. This has an on-board 5v regulator and will power the nano. The rectified DC is feed via a jack plug into the nano expansion board. I used a surface mount device and was able to heat-shrink the assembly into something little bigger than the smoothing capacitor. You can use any small bridge-rectifier such as the W04. This way the nano pulls itself up, and is driven active low by the dcc data signal. The nano pin2 is set as an input with on-board pull up. The resistor limits the current to a safe level if something goes wrong and also guards against current induced lock-ups on the input pin. To protect the arduino input (pin2) we arrange the data feed to be active pull-down via a diode and resistor. This also prrovides a DCC data signal to the unit via a diode and resistor. To power the unit we will rectify the DCC track power to generate a 12v feed. You may also set the servo to power-down after moving, or be continuously powered. You can command individual pins to test a single servo, or emulate a DCC command to test a response to a DCC address. When setting up, you can set the desired servo swing range and also park the servo mid-travel, which is useful to ensure a symetric swing about this. This is the fool proof way of wiring a cross over compared to commoning the servo control on a single output which also requires you to have the mechanical orientation of your servos consistent. This way you can drive a cross over from two outputs each with a servo and not pay attention to the mechanical orientation of the servos, as you can invert one if required, and then assign them the same DCC address. Several outputs can also share the same address, and the output direction can be inverted if required. You can set a DCC address for each output. The unit is programmed through the serial interface. on my own shunting layout I have 12 servos driven off the 10 outputs. If you are driving a cross over where the two sets of points must always either be thrown or closed, then you can common the two servos off the one output. It is capable of driving 10 independent servos, e.g. If you power it this way, there is no need for an opto isolator to couple in the dcc data signal. This unit is powered from the DCC track supply, it draws about 120mA.

My first CW contact on an old Heathkit with a straight key was very exciting at 5 wpm.Low cost DCC accessory decoder to drive 10 servos using an Arduino Nano and a Nano expansion board plus a few discrete components. The more we use Morse code, the better we get. IвЂ™ll be using CW Skimmer more with the Icom 7610. Personally, I use CwGet with N1MM Logger in contests. Listen to W1AW with DM780 and see how much you can translate in your head.

There are many excellent websites and phone apps that can help Hams learn Morse code and how to make CW contacts. If you are a new Ham I would encourage you to learn Morse code and become proficient at a comfortable speed. I look at these programs as learning tools for decoding CW. CwGet is more forgiving and requires less user intervention.

If you are looking for software to help translate Morse code, I suggest trying it. CwGet is a paid program, but it can be tried without registering. Just to give the video below some context I threw in CwGet.
