I just ran across this introduction to Arduino video on YouTube that may be of interest to those who want to know what it's all about. The presentation is fast but comprehensive. There are some good points about how to get started, downloading the software, making sure you have the appropriate drivers, different versions of the hardware, sample code and examples. It's one of the better presentations that I've seen on this topic. You can skip the ending though; it's just a commercial.

I'm just wondering what brand of servo do you guys use for your switch machines? Are they any special variety? Do they have metal gears or plastic? Does Tower Pro sound familiar? How much torque? What about the MG995 or MG996R versions? I need to learn about these.

I think you'll find a vast majority of the servos have some plastic gears.

You don't necessarily need an Arduino to operate servos controlling track switches. A manual servo controller will work as well and is less expensive.

Bob: Didn't you mention somewhere that you had written some magazine articles about servos and things a while back? Can we see them? Can you post them here? Don't do anything that would get you in copyright trouble. I'm just asking. 

Hi Bob; I went back & looked up the article in the Sept 2016 issue of Classic Toy Trains & all I found was a short Vid of  Weekend Edition of a Workshop with a "Gas & Go with a Smart Detector".  Is that what you were referring me to or is there an article about servos? If there was I didn't see it. maybe if you have the article you could post it here on the forum I know many members would love to see it.

The Servo article is on p.52 of the September 2106 CTT. My Gas & Go article was in the February 2016 issue. Hope you can locate it. There was also an article about servo applications for model railroads in the May 2014 issue of Servo magazine.

The least expensive manual servo driver I've used was $5.00. If you can get an Arduino for $2.50, I'd say go for it!

I also live in the land of sunshine and no basements.

Thanks, Bob! The servo testers from overseas look like this:
