ESP8266 01 + Clock Tiny RTC ds1307 + Memory Eeprom 24c32

We will perform the connection of the Tiny Arduino module RTC I2C DS1307 has a real time clock per I2C protocol and an Eeprom memory for storage I2C EEPROM 24C32 32K.

Many thought for a wireless module needs a real-time clock, if you can make requests to a local server via UDP ip, but there are certain applications in which in which there are not always Internet connections and time stamp is required .

The connection to the module ESP8266 01 via 2-wire I2C protocol by GPIO0 and GPIO2 is done, the strategy initially updated MRTC time and then proceeds to make the impression on the serial terminal
