Just so I better understand why I'm doing what I'm doing, why does putting the power to the wiper and getting the inverse split voltages directly from one pot not work?
Is it just too much current through the pot? Even if the pot is fairly high-rated (2W) and the current drawn by the...
StudioT,
I think I know what you mean. The resistor is there to prevent a full 5V at zero resistance from the pot(s)? That would make sense as the actual OEM circuit has a max of 4.87V not a true 5V. The thing I don't know is how to determine the value of that resistor to get my 4.87V, since...
Studiot,
Thanks for your reply. I had pondered ganging up a pair of potentiometers, but dismissed it as a "mechanical" solution rather than an "electronic" one. It is certainly a very straightforward approach that is well within my limited abilities.
Still, it seems unlikely to me that...
Potentiometer as divider: How to use both "sides" of the split voltage?
Hello,
I am building a custom electric vehicle using an existing controller and motor combo.
The controller reads the voltage on two leads to control the speed of the motor and expects the voltages on the two leads...
