With the aid of very little extra hardware we can use Arduino as a DCC decoder, with a price tag that is almost 10x lower than commercially available decoders. In this video we create a DCC Accessory Decoder. In the next video we'll make a DCC Servo Decoder.

In stead of DIY, alternatively you can use the ARCOMORA software, which is fully configurable via a user interface.

Based on the code for the DCC Accessory Decoder we can create a Servo Decoder. All we have to do is add a couple lines of code to toggle the setpoint of the servo, based on the DCC status, and add the code to rotate the servos based on a millis() timer.

With some applications a stepper motor is prefered over a servo. For instance for the continuous rotation of say a wind mill model. Or with applications like a turn table, a linear shift table or an elevator, a stepper motor can be of great help thanks to the accurate positioning that is possible.

In this video we connect a very cheap (less than $2,-) toy motor to our Arduino and run it. In the coming videos we'll look at features like change directon, speed control and accurate positioning, and we'll look at more powerful motors and drivers.
