    dear all i'll start to make a project of a 2DOF with arduino uno and shield i need the scketch of arduino i need some help to start, i see a lot of post and for me it's clear the conetion, the only point that i have doubts is the shield exit that in all of pictures put 12V and the arduino sketch thanks in advance for your help
    kind regards

    Before buying anything decide on the style of 2DOF sim you want to build, a shoulder mount, compact, knee or foot design. Have a play with SimCalc to get your head around physics Vs design: https://www.xsimulator.net/communit...e-linear-speed-and-forces-of-your-design.270/

    You can go through existing member projects for specific ideas or inspiration: http://www.xsimulator.net/community/forums/diy-motion-simulator-projects.22/

    Or search for specific types of projects using the Google Custom Search function on the Recent page: https://www.xsimulator.net/community/find-new/posts?recent=1

    Then have a good read through the Design section of the FAQs: https://www.xsimulator.net/community/faq/design-considerations-resources.24/category

    If something sounds odd then look it up in the glossary: http://www.xsimulator.net/community/faq/glossary-of-acronyms-and-names.66/

    With 24v motors and arduino uno the Sabertooth would be the best option: https://www.xsimulator.net/community/faq/sabertooth-motor-driver-max-36v.271/

    If you go with the Saberetooth 60s you will need a battery to absorb regenerative current, with the 32s you need the correct resistor.

    With 24V you can use cheap LED strip PSUs, you will find plenty on Ebay.

    I would suggest using the soft start SMC3 code for the Sabertooth: https://www.xsimulator.net/communit...ket-serial-pid-motor-driver-w-softstart.9277/

    You can use traditional pots, but I would suggest paying a little more and go with Hall Sensors, as the won't break if over rotated, are very accurate and good durability, something like these spec wise: https://au.element14.com/bi-technol...fs/sensor-hall-0-2v-20v-to-10v-pin/dp/2319662

    403FF735-8009-4289-B9F2-AC08FAF86D85.jpeg Hi thanks for your help, I charge the Arduino sketch smc3 and make the conexions between arduino ,shield and potentiometers , at this step I can test if the potentiometers have movement with simtools? Or it’s necessary connect the motors? The photo is just that I make without motos
    Many thanks

    To test if the potentiometers work correctly it is not necessary to have the motomonster board connected, however, the next step is to test the direction of rotation of the motors, so it is necessary to have everything connected and follow the steps you will find in the first link to attach
