Arduino Clock Sketch Examples

Either copy the Arduino clock sketch below, or download the clock.zip file that contains the Arduino sketch for this project. Copy the clock folder from the zipped file to your Arduino sketchbook folder. Alternatively, copy the text from the enclosed file and paste it into the Arduino IDE. Verify and upload the clock sketch to the Arduino.

This lesson aims to show how to make a simple Arduino based clock using an a LCD and a real time clock. INT - D3INT1 11 12 After loading 13 and starting the sketch, use the serial monitor 14 to see the clock output. 15 16 17 setup see Pcf8563 data sheet. 18 1x 10Kohm pullup on Pin3 19 INT 20 No pullups on Pin5 or Pin6

The simplest Arduino LCD clock ever designed. Only needs an Arduino UNO, a 1602 LCD, and two buttons. No resistors, no potentiometer.

Another example is for an Arduino digital clock or calendar. Arduino-based clocks use the current time as a timer for reminders or to execute a scheduled command via the Arduino's IO pins. Depending on the project, having a way to get the current date and time is very useful. Arduino Sketch. To make it easy for us to develop the code of

Learn how to display time on LCD using Arduino, DS3231 or DS1307 RTC module. How to make an LCD clock. The detail instruction, code, wiring diagram, video tutorial, line-by-line code explanation are provided to help you quickly get started with Arduino. Find this and other Arduino tutorials on ArduinoGetStarted.com.

So now we have our Real Time Clock up and running and we can use in any Arduino Project. As a second example I connected an LCD to the Arduino and printed the time and the date on it. Here's the source code of this example Arduino DS3231 Real Time Clock Module Tutorial Crated by Dejan Nedelkovski

3. Set date and time. To set Date and Time use the following sketch Demonstration of Rtc_Pcf8563 Set Time. Set the clock to a time then loop over reading time and output the time and date to the serial console. I used a RBBB with Arduino IDE, the pins are mapped a bit differently. Change for your hw SCK - A5, SDA - A4, INT - D3INT1 After loading and starting the sketch

So for starters lets connect VCC and ground of the oled display to arduino. Then lets envisage the I2C bus with the Serial Data line called SDA in short and Serial Clock line called SCL. Arduino is connected to that bus via analog pin a4 to SDA and via analog pin A5 to SCL. Microcontroller is a master device.
