RTC I2C DS1307 AT24C32 Real Time Clock Module in Pakistan
What is an RTC?
A real time clock is basically just like a watch – it runs on a battery and keeps time for you even when there is a power outage! Using an RTC, you can keep track of long timelines, even if you reprogram your microcontroller or disconnect it from USB or a power plug.
Most microcontrollers, including the Arduino, have a built-in timekeeper called millis() and there are also timers built into the chip that can keep track of longer time periods like minutes or days. So why would you want to have a separate RTC chip? Well, the biggest reason is that millis() only keeps track of time since the Arduino was last powered – . That means that when the power is turned on, the millisecond timer is set back to 0. The Arduino doesn’t know that it’s ‘Tuesday’ or ‘March 8th’, all it can tell is ‘It’s been 14,000 milliseconds since I was last turned on’.

RTC I2C DS1307 AT24C32 Real Time Clock Module in Pakistan
The DS RTC (Real Time Clock) Module – 1307 is a real-time chip of DALLAS company,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. DS1307 have a programmable waveforms output, it can be used to drive LED lights, 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. Note, this module must be installed on the battery can work normally. The battery is button batteries (type CR2032 will be better), the positive upward: Download the PDF form the link DS 1307.
This tiny module embraces DS1307 time module, DS18B20 temperature module and AT24C32 storage module. DS1307 and AT24C32 are connected to IIC bus. And DS18B20 can be visited via DS pin.
This is a great battery-backed real time clock (RTC) that allows your microcontroller project to keep track of time even if it is reprogrammed, or if the power is lost. Perfect for datalogging, clock-building, time stamping, timers and alarms, etc. The DS1307 is the most popular RTC – but it requires 5V power to work (although we’ve used it with 5V power and 3.3V logic successfully).
