This is the second video in the (JMRI / C/MRI) series that shows how to have control of 4 servos and 2 Led's per servo using C/MRI and JMRI.
The library for Variable speed servo is located at:
github.com/netlabtoolkit/VarS...
The hardware needed is listed below.
Arduino level converter : smile.amazon.com/gp/product/B...
USB to RS-485: smile.amazon.com/gp/product/B...
Arduino Nano: smile.amazon.com/gp/product/B...
Arduino sensor shield:
smile.amazon.com/gp/product/B...
I recommend that you do the below:
1. Follow all standard electronics safety practices
2. Power the Nano with a stable 5 volt external power supply as the LED's and servos can draw a significant current if all are running at the same time..
3. Ask for the code via email.
4. Ask questions if you are not 100% sure.

Lawrence I have tried to do this on a raspberry pi 4b and have had no luck. Any suggestions?

How do i connect more than 13 servos? What pins? I have emailed but have gotten no response. Is this still active?

Larry, what is the RS485 and why is it necessary? I haven't seen this item in any other projects.

Hi Doug, RS485 is a serial protocol wherein you can tie multiple devices to a single RS485 adapter. This is very versatile where you have multiple Arduino's connecting to JMRI. Otherwise, each device would have to have an individual serial port.
