The I2C interface is established as shown in figure. The module can work on +5V regulated power and higher voltage may damage the module. The default circuit diagram of DS3231 RTC module interface is shown below.ДЄs shown in circuit diagram the module is connected to +5V power supply. So we have to get the information of DATE and TIME through this interface. The data is sent to the module or received from the module though I2C interface. With two alarm clock and temperature sensor on board the use of DS3231 module is promoted even further than other modules.ДЄs mentioned earlier the only way to communicate with this RTC module is through I2C interface. The DS3231 can also work on both 24Hr and 12Hr format finding applications in GPS systems. DS3231 RTC MODULE capable of communicating with high speed TWI interface. So this module can be used on mobile systems.Д¬ase3: Where high speed communication is of need. DS3231 RTC MODULE consumes very less power to function. The chip keeps the time up to date more accurately than most modules.Д¬ase2: Where power consumption is issue. Although there are many RTC modules present in the market DS3231 is one of the most popular one because of its accuracy.

Maximum voltage at SDA, SCL : VCC + 0.3VДЇor understanding the use of DS3231 RTC MODULE consider:Д¬ase1: Where you want accurate time and date.

Operating voltage of DS3231 MODULE: 2.3V вЂ“ 5.5V.

CR2032 battery backup with two to three year life.

Automatic power failure battery switch circuitry.

Digital temperature sensor with в“вњ¬ accuracy.

RTC counts seconds, minutes, hours and year.

These four pins are given out on other side of module sharing the same name. So we can have accurate TIME and DATE from RTC module whenever we want.ДS3231 is a six terminal device, out of them two pins are not compulsory to use. RTC modules are simply TIME and DATE remembering systems which have battery setup which in the absence of external power keeps the module running. Arduino Zero has 20 digital I / O pins (10 of which can be used as PWM output.).RTC means Real Time Clock.

Unlike Uno, Zero can only work with a 3.3 V input supply. You can use it in your IoT projects, wearable technologies and robotics projects. The placement of these pins is as follows: Arduino micro pwm pinoutДЄrduino Zero is an advanced version of Arduino Uno. Arduino MicroвЂ™s pwm pins are ДЈ, 5, 6, 8, 10, 11 and 13 pins. It can also be placed on the breadboard easily.The board has 7 pwm channels. It can be programmed with USB cable or RS232-TTL converter. It also has a 16 MHz oscillator, 1 micro USB port, 1 ICSP connection вЂheaderвЂ™ and a RESET button. Arduino Micro has 20 digital I / O pins (7 of which can be used as PWM output, 12 of which can be used as Analog signal input). Arduino Micro Pwm PinoutДЄrduino micro is using ATmega32U4 processor. In Arduino Leonardo pwm pinouts are 3, 5, 6, 9, 10,11 and 13. It has 20 digital input / output pins (7 of which can be used as PWM output, 12 of which can be used as analog input), 16Mhz crystal, micro usb socket, power socket, ICSP connector and reset button. Arduino Leonardo Pwm PinoutДЄrduino Leonardo It is an Atmega32u4 based microcontroller board. In Arduino Nano, PWM pins are 3, 5, 6, 9, 10 and 11. The frequency of the PWM signal on pins 5 and 6 will be about 980Hz and 490Hz on other pins. In Arduino Uno, PWM pins are 3, 5, 6, 9, 10 and 11. Arduino Uno Pwm Pinout ARDUД°NO PWM PINOUT In this article, we will examine the official arduino platforms. There can be many arduino except ArduinoвЂ™s official products. Arduino Pwm PinoutДЄrduino is an open source project. The faster the switching is done, the stronger the signal transmitted by PWM. This control is achieved by switching completely. In addition to the purpose of making the signal information suitable for transmission, it also aims to provide power control and support special circuits such as electric machines, solar cell chargers. In its simplest form, it can be described as a signal modulation technique. Pulse Width Modulation is a technique used in special application areas such as Arduino or electrical machines as well as electronic circuits, such as signal processing or signal transfer.
