Take a sample of the potentiometer with an A0 pin of the Arduino, which has a resolution of 1024 values (10 bits), and convert the potentiometer output voltage into an integer value between the range of 0 to 1023 volts as input. For this purpose, I have used theanalogRead()function. Us...
I found some audio play using this low pass filter at the output port of opa ,so I would like to series a resistor 10o and parallel a cap 50pf, the fc is about 300khz , The reason is that : The last 2nd lowpass filter is located on the front end, there i...
A potentiometer is an analog device. It offers resistance anywhere from nearly 0Ω to its rated resistance value. Voltage gets allocated, according to Ohm's Law, proportionally according to the resistance a component offers. The formula V= IR. It is a direct relationship. Thus, as resistance ...
I am using MC SDK 5.4.4 to drive a PMSM motor using STSPIN32F0601. Now, I want to add a potentiometer to my system to sense different user selectable levels. Generally, in other appplications we can intialize the ADC and read the ADC converted values as and ...

Why is only the potentiometer used to measure emf of cell and not voltmeter? An ammeter measures electric current at a single point in a circuit. A voltmeter measures the electric voltage difference between two points in a circuit. Which has the greater resistance? a. The ammeter. b. The ...
I just want to add that the charger is best not to carry along with the car because the vibration will cause components that are relatively large in quality, such as transformers, Capacitors, high power transistors, field effect transistors, adjustable potentiometers and other loose, resulting in...
We connect pin 6, P1W, the wiper terminal of potentiometer 1, to the output device that we want to turn on. In the case of this circuit, it is the red LED which is in series with a current-limiting resistor. Being that the wiper terminal attaches to this LED, we can adjust the re...
