This is for testing the LED display to verify all are in working condition. The 3 1/2 digits should illuminate "-1.8.8.8" as verification. I think some digital...

We've tried numerous different configurations, including the one you suggested, and are still have some difficulty achieving our objective. I decided to put together a very quick and concise word document explaining in more detail what...

    Does anyone know exactly how to configure them properly though? I hooked them up in what I thought was a series configuration but measured a maximum resistance of only 9.49k ohms. Granted, neither potentiometer's actual maximum resistance was ideal, but the math still doesn't make sense to me...

    Series Potentiometers?

    Hello! I'm controlling a current by changing the resistance using a 10 turn, 10k ohm potentiometer. However, it doesn't give me the precision or amount of control I'd like on the bottom end (for example, from 5mA to 2A out of a total of 52A). The slightest amount of pressure on the knob will...
