A potentiometer is basically a variable resistor. A typical potentiometer has three terminals which can be used in two modes according to the voltage divider principle. The analogy of the infinite resistance, however, is in terms of its use in measuring the EMF of a cell. ...
R2 is a potentiometer that is used to control the sound volume.C2 is a capacitor that sets the voltage gain of the LM386 amplifier. Therefore, the voltage out is 200 times the voltage in. This provides us with the maximum gain that the LM386 can provide.C3...
Potentiometers can be used as voltage dividers. To use the potentiometer as a voltage divider, all the three pins are connected. One of the outer pins is connected to the GND, the other to Vcc and the middle pin is the voltage output. When the potentiometer is used as a voltage divider...
The prototype has a threshold set via potentiometer for convenience. The basic idea is that it’s possible to measure a capacitor’s capacitance using two microcontroller pins and the right software, so by using a few materials to create an open-style capacitor, one can monitor it for changes...

(Notes: a total of six fruit colors are used in the proposed system; an example of three colors of a fruit is shown in Figure 4 together with the corresponding positions and readings of the slide potentiometer for selecting the respective colors. Color 2 is the correct watermelon color. Fig...
A potentiometer is a three-terminal device, so the arrow becomes the third terminal (the wiper). Capacitors There are two commonly used capacitor symbols. One symbol represents a polarized (usually electrolytic or tantalum) capacitor, and the other is for non-polarized caps. In each case there...
