Design the HW and SW of a digital voltmeter using the Arduino board. The microcontroller will read an analog signal generated by changing the position of a potentiometer connected to the Arduino board. Your program should read the analog value and display it on an LCD connected to the board with I$2$C protocol. The range of values for the analog signal shown in the display will be in the range of $0$ to $5$ volts. Make sure that the display does not blink i$.$e$.$ it should be updated only when the potentiometer is moved. Your program should use the interrupt generated by ADC to read the converted value. You should not use pooling, delay functions or Arduino$-$style libraries except for the communication with the LCD display. Provide the final diagram of your system and include the C$++$ code in your report.
