    Potentiometer

    Okay, maybe it's better that I don't use less than 5 voltage, maybe it's better to use 6 voltage at its lowest. There is no other circuit that could affect this controller. These controls are powered by a power supply. I only choose how much the voltage controller goes. I have three options, 5...

    Potentiometer

    I have a question about this bidirectional motor controller. Can this be made to work below 5VDC? I have a few of these controllers and some of them won't even work on 5VDC.

    Ampere/voltagemeter

    I am no longer young and my skill level is definitely the lowest on this forum. Somehow I feel like I don’t get these meter to work very easily. And my skills are not enough. I can't spend too much time trying to get these meter work. These are just a small part of my project. I have options and...

    Ampere/voltagemeter

    I was wondering if I could use relays with the meter. My drawing is poor but somehow this way. I don't know if the yellow wire is still a problem here either? Oh no, I just realized this doesn't work because the voltage from the controller varies and the relay coil doesn't like it :(

    Ampere/voltagemeter

    Maybe this would be one option. Annoyingly, I bought these digital meter many. Has to be some solution to make them work.

    Ampere/voltagemeter

    Okay, it really looks like this diode isn't working here. I'm a little lost with this, really annoying if I bought these meter in vain :( I mean the potentiometer that controls the motor. I'm really afraid I can't do this. My skills are not enough :( Is there any easy way to get these meter to...

    Ampere/voltagemeter

    I don't know if this is the same thing.

    Ampere/voltagemeter

    For some reason, this also shows readings, even without the load (motor) when I turn the potentiometer.

    Ampere/voltagemeter

    I know this is based on a pulse but for some reason this meter shows voltage?!. It will also show something in the amp when I hold the motor shaft and try to stop it, then the current will increase. I don’t know what these readings are but they are enough for me. This drawing of your attachment...

    Ampere/voltagemeter

    Yes it is PWM. I have tried using this meter with it and it works. The only problem is when the polarity changes so the meter does not then show a read-out.

    Ampere/voltagemeter

    That exchange doesn't seem to be very easy? I was wondering if it could somehow work using diodes. Perhaps it is only easiest to use two separate meters.

    Ampere/voltagemeter

    If I put a meter at this point like my drawing, then it shows power 24v? I want to see the volts that go to the motor after the controller. I thought this meter would work like a multimeter and polarity wouldn't matter. Maybe I need to put two on this meter.

    Ampere/voltagemeter

    It doesn't work because I adjust the motor speed and direction bi-directional motor control. I don't think I can put the controller after the meter :(

    Ampere/voltagemeter

    Hello, I have a problem that I need your help with. I bought an amp voltmeter. I want to connect it to show a small dc-motor with volts and amp. But the problem is that the meter will not work if I change the polarity. The direction of rotation of the motor is changed by reversing the polarity...

    Potentiometer

    The solution was found closer than I could imagine. I found an old joystick potentiometer. It looks bigger compared to other potentiometer. I check those multimeter and I get 110k ohms. This potentiometer work those angle which I want. But why do these pots work differently? Are joystick pots...

    Potentiometer

    Okay, I'll try this tomorrow. I still have to ask if I understood correctly, so can I add those new two resistors to something between 1k -10k? Thanks :)

    Potentiometer

    Hi, I would like to try this. Would it be possible for you to show (draw) how this is done for example in this picture you added? I’m a girl and this isn’t my strongest skill, not yet at least :) I'm afraid if I destroy this controller by doing wrong :( I want to be sure what I do. I know how...

    Oh I guess I don't know how to do that :(

    Potentiometer

    I already mentioned it above in the post. Because I want use joystick and the trajectory of the joystick is not enough.
