const int bit_D = 5;

void setup()

pinMode(bit_D, OUTPUT);

// ALL pins LOW at the start of program

digitalWrite(bit_A, LOW);

digitalWrite(bit_B, LOW);

digitalWrite(bit_C, LOW);

digitalWrite(bit_D, LOW);

}

void loop()

{

char i=0; // variable "counter"

for(i=0; i

{

}

void counter(char digit)

{

// Making low previous digit

digitalWrite(bit_B, LOW);

digitalWrite(bit_C, LOW);

digitalWrite(bit_D, LOW);

In the previous lab, we developed a binary to seven-segment display decoder using TinkerCad. A binary counter, created on a virtual Arduino, was used to as the input to a CD4511BE decoder chip that translates the counter to the seven digital signals needed to display the binary count in the form of digits from 0 to 9. The objective of this lab is to read an analog input pin, map the result to a number between 09 and display that number on the seven-segment display. The pre-lab focuses on the code required to do this
