If an error occurs, this can be used to distinguish between a DS1307 that is not running vs no chip connected at all.ĭS1307RTC includes 2 examples, to read or set the time. Returns true if a DS1307 compatible chip was present after using the 4 functions. Sets the date & time, using a TimeElements variable. Returns true on success, or false if the time could not be read. See the Time library for TimeElements details. Read the current date & time as TimeElements variable. Returns true for success, or false if any error occurs. Sets the date & time, using a 32 bit "time_t" number. If the time zone is not set or is set incorrectly, the time in the chart will. Zero is returned if the DS1307 is not running or does not respond. Reads the current date & time as a 32 bit "time_t" number. You can then run the ReadTest example to make sure that the time was set. Run this program to set the time of your RTC to the current time on your computer. The DS1307 serial real-time clock (RTC) is a. In the DS1307RTC library examples folder there should be a program called "SetTime". In my 15th library, I will show you, how to operate with DS1307 Real Time Clock I2C module from maxim integrated. I used the DS1307RTC library and the Time library to program my DS1307.Īrduino DS1307RTC library can be found at: You need to run a program to set the time on the RTC to initialize it. Gnd should connect to ground, Vcc should connect to the Arduino's built in 5V supply, Sda should connect to A4 (analog pin 4), and Scl should connect to A5 (analog pin 5). DS1307 based RTC with LIR2032 battery (Battery included).The lithium ion battery included with the DS1307 board should last a couple years.Īrduino Tiny I2C RTC DS1307 AT24C32 Real Time Clock module+board for AVR ARM PIC It runs off of it's own battery, so even if the alarm clock is not plugged in, the RTC will keep the current time. It keeps track of the hour, minute, second, day, month, and year. Note: Multiple libraries are available through the library manager within the. The DS1307 RTC is a chip that keeps time. The DS1307 serial real-time clock (RTC) is a low-power, full binary-coded. I2C RTC DS1307 AT24C32 Real Time Clock For Arduino Raspberry Pi
