Make a new time object to set the date and time. Initialize a new chip by turning off write protection and clearing the #DS1302 H ARDUINO LIBRARY DOWNLOAD SERIAL#Print the formatted string to serial so we can see the time for debuging Format the time and date and insert into the temporary buffer. Get the current time and date from the chip. assignments for the Arduino as well for as the DS1302 chip. Set the appropriate digital I/O pin connections. ![]() Example sketch for interfacing with the DS1302 timekeeping chip. Programĭownload the required arduino libraries and to the libraries. Refer the schematic diagram above for details. Circuit/Schematicīoard connections are simple and self explanatory. ![]() Parts requiredįor this project we need 3 important parts viz: Arduino, any RTC clock module(I have used DS1302), 7 segment 4 digit tube display. Unlike other posts where I had used lcd display. Then, we print the strings to the serial monitor.Īt the end of each loop iteration, the program pauses for one second so it doesn't read too fast.In this arduino clock project we are displaying time on 7 segment tube display. To get the date as a string (dd/mm/yy format), and timeStr() to get the time as a string In the loop function, we use dowAbbr() to get the day of week abbreviation, dateStr() The last line of the setup function opens a serial port: Serial.begin(9600) // Open serial port Rtc.setDate(day, month, year, dayOfWk) Parametersĭay: The day of month to set (uint8_t, 1-31)ĭayOfWk: The day of week to set (uint8_t, 1-7) (use the weekday constants: SUNDAY, Second: The second to set (uint8_t, 0-59) Minute: The minute to set (uint8_t, 0-59) Rtc.setTime(hour, minute, second) Parameters Next, we call setTime() and setDate() to set the time and date of #include // Include the libraryīefore writing to the RTC's registers, we need to disable its write protect by calling setWriteProtect(false) rtc.setWriteProtect(false) RTC's CLK pin is connected to, and cePin is the Arduino pin that the RTC's CE pin isĬonnected to. dataPin is theĪrduino pin that the RTC's DAT pin is connected to, clockPin is the Arduino pin that the Parameters in the order (dataPin, clockPin, cePin). The first step is to include the library and create a DS1302 object (called rtc). Run the code, then open the serial monitor. Test - Print Date and TimeĪfter installing the library, go to File > Examples > DS130X > DS1302 > DateAndTime > PrintDateTime #DS1302 H ARDUINO LIBRARY DOWNLOAD INSTALL#To install this library, open the Arduino IDE, then go to Sketch > Manage libraries > Add ZIP library, then go to your downloads folder and select the downloaded ZIP. The library in Zip format | DS130X Documentation This tutorial requires my DS130X library. ![]() This is why a 32.768 kHz oscillator (Y1) isĪttached to pins 1 and 2. The DS1302 keeps track of time by reading ticks from an oscillator. This supply will allow the DS1302 to keep track of time when it Note that the backup supply is a 3V coin cell.
