2. Check the connection of the CLK and RST pins according to the specifications in the DS1302 datasheet.
3. Load the example sketch provided with this tutorial onto the Arduino.
4. Open the Serial Monitor in the Arduino IDE to view the time and temperature data.
5. Configure the digital clock via code or hardware interface (check the datasheet).
6. Verify the correct reading of the temperature sensor connected to the DS1302 module.
7. Test additional features such as voltage monitoring if available.
8. Adapt the sketch to integrate time and temperature data into your project.

Example code

/*
 * Esempio base per utilizzare il modulo DS1302
 */
#include <DS1302.h>
DS1302 rtc(9, 8, 7); // definisci i pin collegati al modulo
void setup() {
  Serial.begin(9600);
}
void loop() {
  DateTime now = rtc.now();
  Serial.print(now.year(), DEC);
  Serial.print("-");
  Serial.print(now.month(), DEC);
  Serial.print("-");
