Tutorial: How to use PCF8563T IC (RTC) with Arduino

The PCF8563T IC is an RTC for storing time and date. Perfect for projects that require keeping track of time.

What you need

• Arduino Uno
• USB A-MicroB cable
• PC with Arduino IDE software installed

Steps

1. Install the RTClib library in the Arduino package manager
2. Connect the PCF8563T IC to the SDA and SCL pins of Arduino
3. Include the RTClib library in the code
4. Create an RTC object
5. Read the current time with rtc.now()
6. Print the time on the serial monitor

Example code

include <RTClib.h>

RTC_DS3231 rtc;

void setup () {
  Serial.begin(9600);
}

void loop () {
  DateTime now = rtc.now();
  Serial.println(now.unixtime(), DEC);
}

Mini project

Create a digital clock with an LCD display that shows the time and date

Common mistakes

• Connection error of SDA and SCL pins
• RTClib library not installed correctly

Recommended accessories

• 16×2 LCD Display
• CR1220 Backup Battery
• 4.7kΩ Pull-up Resistor
• JTAG Debug Cable
