Before I start this, im trying to verify to to display the value of the voltage on a pair of 7-segment displays and round off and not truncate the values. Im not sure how that would work, if somebody can help me that would be appreciated
Also I need to test the voltmeter by using a potentiometer to generate a smoothly varying voltage across the entire 0 – 5V range. And I am going to add a extra red LED to act as a leading decimal point. And change my code so that voltages in the range 0.0 – 0.99V are displayed using an assumed leading “0” ie. using the two digits for two decimal places; voltages of 1.0V and above are displayed.
And in order to test my voltmeter again by using the potentiometer to generate a smoothly varying voltage across the entire 0 – 5V range, taking particular note of the range 0 – 1V. How would I do that?
