DCC-EX command station using servo and LED #667

Sent by Umberto Bianchi (umbianchi@gmail.com). Created by fire.

Good morning,
I started using DCC-EX command station with Arduino mega 2560 + arduino motor shield + PCA 9685.
I would like to test 1 servo and 1 green LED to be able to manage 1 TURNOUT, using Arduino serial monitor.

I know the command for the servo
<D SERVO 100 105> but I haven't found any examples for using with the LED.
any help is welcome.
Thanks in advance

The additional line in mySetup.h is only needed for LEDs connected to PCA9685. LEDs connected to other pins/VPins will require a resistor to limit current.

in mySetup.h IODevice::configureServo(112,2437,0,PCA9685::NoPowerOff); and upload the sketch

You can use commands from the serial monitor to test. <z 112> <z -112>
