Code

#include <DS1302.h>
 
// Init the DS1302
// DS1302 rtc([CE/RST], [I/O], [CLOCK]);
DS1302 rtc(8, 7, 6);
 
void setup() {
  // Set the clock to run-mode, and disable the write protection
  rtc.halt(false);
  rtc.writeProtect(false);
  
  // Setup Serial connection
  Serial.begin(9600);
 
  // The following lines can be commented out to use the values already stored in the DS1302
  rtc.setDOW(FRIDAY);        // Set Day-of-Week to FRIDAY
  rtc.setTime(12, 0, 0);     // Set the time to 12:00:00 (24hr format)
  rtc.setDate(6, 8, 2010);   // Set the date to August 6th, 2010
}
 
void loop() {
  // Send Day-of-Week
  Serial.print(rtc.getDOWStr());
  Serial.print(" ");
  
  // Send date

  Serial.print(" -- ");
 
  // Send time
