Hi Paul/Forum, I've noticed some strange behavior of analogread. Changing the voltage at one pin influences the readout of the next pin being read. The circuit consists of 4 potentiometers (104k) wired to analog pins 0 to 3. The graphs are made with Processing using a modified version of the...

Well, I simulated it with Qucs (very neat open source simulator) and it looks like Paul's suggestion is exactly what I need! I do have some scrap parts at home but I'm at work now so I can't test it anyway. But the store I always order from sells exactly those parts, so that's covered. I did...

Yes, I should have specified, sorry: the variable resistor is completely removed from the old circuitry. I'll take some time to process your answers. Thanks a lot for the quick replies!

Hi all. I just purchased a Teensy 3, primarily to resurrect a prehistoric PC racing wheel. I'm pretty new to electronics (I know Ohm's law and... well, let's leave it at that for now ;)). The problem is that the steering axle uses a two-terminal (linear) variable resistor (rheostat?) (110k, 55k...
