Being aclose relative of resistors, thesymbol of a potentiometeralso looks very similar to a resistor.TheSymbol of the potentiometer is given in the below image, it will have a resistor and an arrow pointing towards the resistor, the arrow represents the sliding contact of the POT. The two ...
A preset or a trimpot is exactly identical to a potentiometer, and is designed to work the same way as pots do, expect the fact that a preset does not have a long, hand operable shaft, rather these devices are intended to be operated (rotated) using a a screwdriver spindle through a ...

How does a MIDI controller work? To understand what data a MIDI controller sends data to computers, let’s break down the essential elements of MIDI controllers. How does a MIDI controller connect to a computer? A USB Type B cable, sometimes known as MIDI over USB cable, allows us to co...
How does a Torque Sensor work? How to measure torque? Firstly, we need to understand the underlying physics and material science behind the torque sensor working principle, which is the strain gauge (aka Strain gage). Metal foil strain gauge is a force transducer whose electrical resistance vari...
The LEDs must be low-current, because the maximum current that can pass through any of the potentiometer terminals is 2.5mA. Since the power we are working with does not exceed 2.5mA, we do not exceed the specifications of the chip. Our power is 5V-1.65V/1.5KΩ= 0.00223A or 2.23mA....
Digital potentiometers (digiPOTs) are versatile and can be used in a wide variety of applications, for example, for filtering or generating ac signals. However, sometimes the frequency must be able to be varied and adapted to the desired application. Programmable solutions enabling the freq...
