the potentiometer has the circular resistance material over the surface and a knob compress on the same material. A potentiometer, henceforth referred to as a pot, is a variable resistor. The analog input pin converts the voltage (between 0v and VCC) into integer values (between 0 and 1023), called ADC value or analog value. Arduino's pin A0 to A5 can work as analog input. and you will see the changes in the system. The map() function can only be used to rescale the analog value to the int or long type value. This input is translated to a number of glowing LEDs using Arduino Map Function. In this example, using a volume on the master side, we control the servo motor on the slave side. Analog: 281, Voltage: 1.37 Circuit design Arduino use Potentiometer created by masumcis with Tinkercad for example at one point you need 1k resistance and after sometimes you need 3k there. The analog input pin converts the voltage (between 0v and VCC) into integer values (between 0 and 1023), called ADC value or analog value. Tthis project is going to show you how to make Bluetooth led control with lcd beside the Arduino sowing the new led status.
