Boards including the Uno, Duemilanove, Diecimila, Nano, and Mega have a chip to convert the hardware serial port on the Arduino chip to Universal Serial Bus (USB) for connection to the hardware serial port. Other boards, such as the Mini, Pro, Pro Mini, Boarduino, Sanguino, and Modern ...
Arduino Uno Board, 16×2 LCD Module, and a DS3231 RTC module. DS3231 uses SDA (Data Pin) and SCL (Clock Pin) only because of the I2C protocol. This module is designed to communicate using the I2C protocol. So, at first, find the SDA and SCL pin of your Arduino uno or compatible...
