DS1307 is a real-time chip which adopt I2C protocol to communicate with SCM, and there was this kind interface on Arduino, therefore is very convenient to link with each other; This product can be used to drive LED lights, as it have a programmable waveforms output, or trigger a certain event as a break off, but be careful when you use it to take some kind of high power module; We design the real clock module to pin out the I2C interface of DS1307 and programmable waveforms output interface SQW are connected, but usually we will only use the I2C interface to realize basic set the clock/read function.
This module communicate with Arduino through the I2C interface. This module can be used with Arduino Special Sensor Shield V4. You can do some simple design about it, support "plug and play".
In circuit connection, we can use Arduino sensor shield V4 board, but set the corresponding jumpers wires to IIC position.
Real-time clock (RTC) counts seconds, minutes, hours, date of the month, month, date of the week, and year with leap-year compensation valid up to 2100 56-byte, battery-backed, nonvolatile (NV) RAM for data storage; Two-wire serial interface; Programmable square wave output signal; Automatic power-fail detect and switch circuitry; Consumes less than 500nA in battery backup mode with oscillator running;Optional industrial temperature range: -40~85'C;Available in 8-pin DIP or SOIC Underwriters Laboratory (UL) recognized.
