    I'm in trouble!
    Does anyone know why one of the potentiometers when turning in one direction activates both motors and the other direction activates only one. The other potentiometer starts only one engine and perfectly. Help, I was satisfied that my first system had worked correctly and not now. :(

    Estou com problemas!

    Possibly a ground isolation issue.

    Did you check on SMC3 how is the line of this strange potentiometer? Is he in his zone?

    --------------------
    Você verificou no SMC3 como está a linha desse potênciometro estranho? Será que ele está dentro da zona de metição dele?

    I'll check all the connections again and change pots.

    That's right! You need to try to isolate the problem.

    Oi, sou brasileiro e também estou começando a montar um simulador. Nao queria montar usando motor de limpador mas nao consigo encontrar motores aqui no Brasil. Algum brasileiro pode me ajudar com algum link. Obrigado

    you need to post in English too. The link for the engines he used are on the first page of the post.

    I apologize, I wrote on the google translator and when I played on the page it was translated into Portuguese because it was enabled for translation on the page. I won't make that mistake anymore. Thank you

    Hi. I still haven't been able to test the engines correctly to give an opinion on the ones I bought. But they are slightly better than cleaners and do not have to be disassembled to isolate the soil.

    ----
    Olá. Ainda não consegui testar os motores corretamente para dar uma opinião sobre os que comprei. Mas eles são um pouco melhores que os de limpadores e não precisam desmontar para isolar o terra.

    I didn't even start assembling, I couldn't find engines here in Brazil, I only found the ones you are using and the cleaner ones. I found some mounts with 3000 rpm with 1.75Nm of torque and 500w of power. However they are expensive, and it is still necessary to use a reduction box of 50: 1, so that the bricadeira is expensive if you are going to do with this configuration, motors and reduction box go over 2000.00 reais.

    Something is burning my Arduino board. I checked and redone all the calls and I can't find the problem, I got discouraged. Does anyone have an idea?
    Ground structure? Land Monster plate?
    Thank you.

    Algo está queimando minha placa Arduino. Conferi e refiz todas as ligações e não encontro o problema, desanimei. Alguém tem uma ideia?
    Aterrar estrutura? Aterrar placa Monster?
    Obrigado.

    Have you considered ground isolation issues, as per my earlier comment?

    It has already happened to me to burn the arduino by plugging some component in it while it was connected to the USB. It was a Stepper Motor controller.

    I always turn everything off when I need to connect something.

    Some details, now we just have to disassemble, adjust and finish painting and fixing all the components.

    Final considerations.
    I want to thank everyone who shared their knowledge, especially those who responded and helped me directly on the forum. Thank you!

    Unforeseen
    A) First burning of the Arduino and burning of the H Bridge.
    Cause:
    Potentiometer badly fixed, in the test of operation it turned and joined the wiring that was not isolated causing the burning of the components.
    Solution:
    Isolate potentiometer connections and fix them correctly.

    IMG_E1391.JPG


    B) Second burning of the Arduino.
    Cause:
    The housing of the energized source touched the structure causing the component to burn.
    Solution:
    Isolate and secure the source in a safe place.

    IMG_E1392.JPG


    C) Difficulty in configuring movement in SMC3, faulty movements.
    Cause:
    Potentiometers were disassembled to remove the 180 ° swing lock and when assembled they probably must have been twisted in the system causing poor energy distribution.
    Solution:
    Do not disassemble, if disassemble take great care in disassembly and assembly, as they are very sensitive.
    Use pots of excellent quality.


    Main Equipment Costs:
    2 12v motors - $ 71
    1 Arduino Uno - $ 10
    1 H Monster Bridge - $ 14
    2 Potentiometers - $ 3
    1 Source 50A - $ 13
    4 M10 bearings - U $ 16
    Total: - $ 127.00
    The rest of the materials I used scraps and leftovers that I had.

    My weight
    65KG

    *Good luck to everyone!
