I'm trying to use a simple voltage divider to allow me to measure a variable resistance that ranges from around 10k ohm down to nearly zero using an Atmel microcontroller ( like in an Arduino ).

Universal had a number of industry " firsts ", including such products as the " Dynamic Variable Resistance " technology that varied the resistance applied to muscle groups by an exercise machine throughout the entire range of motion.

Most of the digital control in the analog processing chain was done with multiplying Digital-to-Analog converters ( MDACs ) employed as variable gain / variable resistance elements, with analog switches, and with relays.

He does or should get some credit for explaining the microphone effect as being due the the variable resistance of an imperfect contact, rather than earlier explanations of it being due to variable resistance in the bulk carbon.

Five days later, on February 19, Zenas Fisk Wilber, the patent examiner for both Bell's application and Gray's caveat, noticed that Bell's application claimed the same variable resistance feature described in Gray's caveat.

The selenium cell took the place of a carbon microphone also a variable-resistance device in the circuit of what was otherwise essentially an ordinary telephone, consisting of a battery, an electromagnetic earphone, and the variable resistance, all connected in series.

The effect of the increased resistance ( compared to stoma breathing without HME ) in laryngectomy patients is poorly understood, but HMEs add a variable resistance to the airflow resistance, depending on the flow rate, though the outcomes of studies are not consistent.

On March 10, 1876, when Bell and Watson tested their first successful water transmitter, Bell used a needle in the water to minimize the inertial mass moved by the diaphragm and relied on variable resistance in the meniscus of the water on the needle.

While honeymooning in Europe with his bride Mabel Hubbard, Bell likely read of the newly discovered property of selenium having a variable resistance when acted upon by light, in a paper by Robert Sabine as published in " Nature " on 25 April 1878.
