Task: Write an Arduino code to take voltage measurements across a potentiometer in a voltage divider circuit such as thee one built in class. Your code must also use the voltage divider equation to determine the resistance across the potentiometer. The code will record the Voltage and the Potentiometer Resistance measurements in the Serial Monitor. Assume R1 = 47 k0. The Serial Monitor window must give out the Voltage and Resistance values in different tabs, making a "table" such as...
