What is the use of the potentiometer on the I2C module of the LCD …

WebThe LCD volt meter uses the microcontroller power supplies as reference voltages and so it is not likely to be very accurate (e.g. a 7805 5V regulator has an accuracy of 4%). To improve accuracy add a voltage reference and feed the reference voltage to the Vref input on the PIC which is into RA3 ( change the control register values in the ADC to use the Vref). Web9 Nov 2024 · A potentiometer is a device that measures the difference in potential between two points in a circuit. As we all know, the amount of labor involved in moving a charge from one location to another is the potential difference. When a circuit has a potential difference, current flows through the circuit.
