Creating digital clock

I’m trying to create a digital clock simulated in the Virtual BreadBoard Environment.

I have found a few approaches and I think this one should work that I have typed up but I’m getting error messages that make no sense.

If anyone has had any experience with VBB and has anything to say about that please let me know.

But here’s what I have and should this code work?

  The circuit:
 * LCD RS pin to digital pin 12
 * LCD Enable pin to digital pin 11
 * LCD D4 pin to digital pin 5
 * LCD D5 pin to digital pin 4
 * LCD D6 pin to digital pin 3
 * LCD D7 pin to digital pin 2
 * 10K resistor:
 * ends to +5V and ground
 * wiper to LCD VO pin (pin 3) 

	#include <LiquidCrystal.h>
	#include <DateTime.h>

	// initialize the library with the numbers of the interface pins
	LiquidCrystal lcd(12, 11, 2, 3, 4, 5) ;

void setup() {	
	//Set time

void loop() {
		unsigned long prevtime;                       
		prevtime =;                      im getting and error here saying DateTime not definied in current context
		while( prevtime ==;
}                                                   this line saying i need a semi colon
void printDigits(byte digits){
	if(digits < 10) lcd.print('0');
	lcd.print(digits, DEC);
void  digitalClockDisplay(){
	lcd.print(DateTime.Hour, DEC);                   Then this and the following two lines saying cannot resolve
	printDigits(DateTime.Minute);                     DateTime.XXXX

Is my code correct? This is the first time I’m using VBB or Arduino.

I have come across some other ways to do it.

Would trying to use the Time library be a better idea and if so could someone help me in the right direction?


Looks like the library for
#include <DateTime.h>
is not included in your \arduino\libraries folder.

I was curious to if that was it... However I'm looking through VBB and don't see a way to add a library to it.

Does anybody have any idea on how that would work or an alternative way to put a header file into it?

Does VBB let you add a virtual RTC?

I'm not sure what you mean by that. I'm new to VBB and arduino.
