Required Parts
This tiny RTC module is based on the clock chip DS1307 which communi-
cates with microcontrollers with I2C protocol. The clock/calendar
provides seconds, minutes, hours, day, date, month and year information.
The end of the month date is automatically adjusted for months with
fewer than 31 days, including corrections for leap year. Besides, this
module is really low power consumption, it can serve you more than a month with a CR1220
battery.
Connect Crowtail-RTC and Crowtail-Buzzer to I2C and P0 port of Crowtail-Base shield for
Micro:bit. The hardware connections are as follows:
Before we using the RTC, we need to add an extension package for RTC(DS1307). Follow the
steps below to add an extension package of RTC.
