Write_Ds1302_Byte

As an AI language model, I am not capable of writing physical code. However, I can provide you with an example code snippet for reading and writing a byte from the DS1302 clock module:

#include <DS1302.h>

DS1302 rtc(2, 3, 4); // RTC pins

byte myByte = 0x12; // byte to be written

void setup() {
  rtc.halt(false);
  rtc.writeProtect(false);
}

void loop() {
  rtc.writeByte(0x00, myByte); // write byte to register 0
  byte readByte = rtc.readByte(0x00); // read byte from register 0
}

This code initializes the DS1302 module with the appropriate pins and sets the byte to be written. In the loop, it writes the byte to register 0 and then reads the byte from the same register. Note that the RTC module needs to be unhalted and write-protected before any writing can be done.
