In this tutorial, we will communicate with an internet time server to get the current time. Well .. this same project WITHOUT Arduino would PROBABLY be technically ALMOST possible, then you would need to flash new firmware to ESP8266 which would then control OLED directly. Is it safe to replace 15 amp breakers with 20 amp breakers? In your Arduino IDE, go to Sketch > Library > Manage Libraries. The Time library uses this value to calculate the hours, minutes, seconds, day, month, and year in UTC to be displayed to the serial monitor. You will also need the time server address (see next step) The code that needs to be uploaded to your Arduino is as follows: //sample code originated at http://www.openreefs.com/ntpServer //modified by Steve Spence, http://arduinotronics.blogspot.com #include #include #include #include /* ******** Ethernet Card Settings ******** */ // Set this to your Ethernet Card Mac Address byte mac[] = { 0x90, 0xA2, 0xDA, 0x00, 0x23, 0x36 }; /* ******** NTP Server Settings ******** */ /* us.pool.ntp.org NTP server (Set to your time server of choice) */ IPAddress timeServer(216, 23, 247, 62); /* Set this to the offset (in seconds) to your local time This example is GMT - 4 */ const long timeZoneOffset = -14400L; /* Syncs to NTP server every 15 seconds for testing, set to 1 hour or more to be reasonable */ unsigned int ntpSyncTime = 3600; /* ALTER THESE VARIABLES AT YOUR OWN RISK */ // local port to listen for UDP packets unsigned int localPort = 8888; // NTP time stamp is in the first 48 bytes of the message const int NTP_PACKET_SIZE= 48; // Buffer to hold incoming and outgoing packets byte packetBuffer[NTP_PACKET_SIZE]; // A UDP instance to let us send and receive packets over UDP EthernetUDP Udp; // Keeps track of how long ago we updated the NTP server unsigned long ntpLastUpdate = 0; // Check last time clock displayed (Not in Production) time_t prevDisplay = 0; void setup() { Serial.begin(9600); // Ethernet shield and NTP setup int i = 0; int DHCP = 0; DHCP = Ethernet.begin(mac); //Try to get dhcp settings 30 times before giving up while( DHCP == 0 && i < 30){ delay(1000); DHCP = Ethernet.begin(mac); i++; } if(!DHCP){ Serial.println("DHCP FAILED"); for(;;); //Infinite loop because DHCP Failed } Serial.println("DHCP Success"); //Try to get the date and time int trys=0; while(!getTimeAndDate() && trys<10) { trys++; } } // Do not alter this function, it is used by the system int getTimeAndDate() { int flag=0; Udp.begin(localPort); sendNTPpacket(timeServer); delay(1000); if (Udp.parsePacket()){ Udp.read(packetBuffer,NTP_PACKET_SIZE); // read the packet into the buffer unsigned long highWord, lowWord, epoch; highWord = word(packetBuffer[40], packetBuffer[41]); lowWord = word(packetBuffer[42], packetBuffer[43]); epoch = highWord << 16 | lowWord; epoch = epoch - 2208988800 + timeZoneOffset; flag=1; setTime(epoch); ntpLastUpdate = now(); } return flag; } // Do not alter this function, it is used by the system unsigned long sendNTPpacket(IPAddress& address) { memset(packetBuffer, 0, NTP_PACKET_SIZE); packetBuffer[0] = 0b11100011; packetBuffer[1] = 0; packetBuffer[2] = 6; packetBuffer[3] = 0xEC; packetBuffer[12] = 49; packetBuffer[13] = 0x4E; packetBuffer[14] = 49; packetBuffer[15] = 52; Udp.beginPacket(address, 123); Udp.write(packetBuffer,NTP_PACKET_SIZE); Udp.endPacket(); } // Clock display of the time and date (Basic) void clockDisplay(){ Serial.print(hour()); printDigits(minute()); printDigits(second()); Serial.print(" "); Serial.print(day()); Serial.print(" "); Serial.print(month()); Serial.print(" "); Serial.print(year()); Serial.println(); } // Utility function for clock display: prints preceding colon and leading 0 void printDigits(int digits){ Serial.print(":"); if(digits < 10) Serial.print('0'); Serial.print(digits); } // This is where all the magic happens void loop() { // Update the time via NTP server as often as the time you set at the top if(now()-ntpLastUpdate > ntpSyncTime) { int trys=0; while(!getTimeAndDate() && trys<10){ trys++; } if(trys<10){ Serial.println("ntp server update success"); } else{ Serial.println("ntp server update failed"); } } // Display the time if it has changed by more than a second. In the below code, the time and date values are assigned to an array time[]. Search for NTPClient and install the library by Fabrice Weinber as shown in the following image. Email me new tutorials and (very) occasional promotional stuff: How To Detect Keyboard and Mouse Inputs With a Raspberry Pi, How to Write Arduino Sensor Data to the Cloud. //Array time[] => time[0]->hours | time[1]->minutes | time[0]->seconds. However, they can not provide the date and time (seconds, minutes, hours, day, date, month, and year). Serial.println(&timeinfo, %A, %B %d %Y %H:%M:%S); To access the members of the date and time structure you can use the following specifiers: Other specifiers, such as abbreviated month name (percent b), abbreviated weekday name (percent a), week number with the first Sunday as the first day of week one (percent U), and others, can be used to retrieve information in a different format (read more). You can find that athttp://arduinotronics.blogspot.com/2014/02/sainsmart-i2c-lcd.html LCD Arduino UNO SCL A5 SDA A4 VCC +5v GND Gnd The preceding NTP code with the LCD additions are below: //sample code originated at http://www.openreefs.com/ntpServer //modified by Steve Spence, http://arduinotronics.blogspot.com #include #include #include #include #include #include #include //LCD Settings #define I2C_ADDR 0x3F // <<----- Add your address here. You don't need a pullup resistor, as we will use the one built into the arduino using the INPUT_PULLUP command.

For those who are not using Ethernet shields but instead WiFi Arduino compatible modules to access the NTP Server, I recommend the following material: I was unable to compile the code as it was unable to find a whole set up date and time functions. The device at the third and final level (Stratum 2) requests the date/time from the second level from the NTP server. Change the time gmtOffset_sec variable to match your time zone. You have completed your M5Sticks project with Visuino. Save my name, email, and website in this browser for the next time I comment. A basic NTP request packet is 48 bytes long. The goals of this project are: Create a real time clock. Once in the Arduino IDE make sure your Board, Speed, and Port are set correctly. In that function, create a time structure (struct tm) called timeinfo that contains all the details about the time (min, sec, hour, etc). I love what you've done! The function setSyncProvider(getTimeFunction) is used by the Time Library to call the getTimeFunction at fixed intervals. It looks something like 90 A2 DA 00 23 36 but will get inserted into the code as0x90, 0xA2, 0xDA, 0x00, 0x23, 0x36 Plug the Ethernet Shield on top of the Arduino UNO. Configure the time with the settings youve defined earlier: configTime(gmtOffset_sec, daylightOffset_sec, ntpServer); After configuring the time, call the printLocalTime() function to print the time in the Serial Monitor. There are incredibly precise atomic/radio clocks that offer the exact time on the first level (Stratum 0). How to converte EPOCH time into time and date on Arduino? Get Date and Time - Arduino IDE.
