A quick question

dirtdiver

Hi everyone,

i was wondering if i can get readings from one potentiometer on two separate devices- like in my case a teensy and a USB PC steering wheel?

i was considering diods or pots twise the resistance they were but im not really sure what would be correct

Any help is appreciated

    The short answer is yes.

     

    If the potentiometer produces a voltage, (it will be connected to the +ve rail and ground) then you could split it via two resistors to each device.

    This is probably going to impact on both circuits, and both devices need to run on the same voltage and have their ground pins tied together.

     

    The easier way is to use dual potentiometer. These have a single shaft and two seperate variable resistance elements.

    Both devices will be isolated from each other.

     

    A quick check shows a number of types with varying prices.

     

    Hope this helps
