Build a DCC++ base station

Unfortunately, sometimes things don't go quite as they should. Check the following:

1. Does the Arduino work? Remove the motor shield and try to upload a simple blink sketch via the Arduino IDE.
2. Is your hardware supported by DCC++? DCC only supports the Arduino UNO and MEGA in combination with the Arduino Motor Shield or the Pololu MC33926.
3. Is the motor shield getting power (and enough)? You usually need at least 12V. In some cases this is also 15V.
4. Is there a connection between the motor shield and the track? Turn off the power and use the continuity test function of your multimeter to check.
5. Have you connected the jumpers as described in the Hardware chapter?
6. Have you set the locomotive number correctly in the controller software? If you never changed this, it defaults to 3.
7. Is the controller connected to the base station?
8. Did you turn on the power button?
