Real Time Clock : Arduino UNO + DS3231 Rtc Module + LCD 20x4 I2C: In this project, the DS3231 (real time clock) module has been used to get the current time, date and temperature. The Enable pin will be connected to pin number 2 and the RS pin will be connected to pin number 1. begin(16,2); //Defining 16 columns and 2 rows of lcd display. I expect the code to be incompatible and the same goes for the wireing. With each pulse from SCL, SDA sends data from the board to the screen. The hd44780 library is the best available for I2C LCDs. The internal pullup resistors (Rpu= 20~50kΩ) are pretty much weak and not sufficient. LEDs have typical usable lifespan that can be 20k to 50k hours depending on LED and brightness. If a display is for more than 80 characters, it might have two HD44780 drivers that need to be driven by your Arduino hardware. #include <Wire. Upload the downloaded code.
