Rtcds3231 With 1602 Lcd I2c Arduino Project Hub Set up your breadboard circuit with this circuit diagram containing the ds3231 module, i2c lcd and four push button switches with 10 kilo ohms pull down resistors, all connected to the arduino nano. the arduino nano uses pin a4 for sda and pin a5 for scl i2c communication. connect the scl pin of the module to pin a5 of the arduino nano. Step 3: writing the arduino code. here is the complete code to get the ds1302 rtc module working with your arduino and display the time on an i2c lcd. #include <wire.h> #include <ds1302.h> #include <liquidcrystal i2c.h> initialize the ds1302 const int ce pin = 5; const int io pin = 6;.
How To Simply Use Ds1302 Rtc Module With Arduino Board And Lcd Screen Step 4: video vidéo. 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. they are al displayed on the 20x4 lcd screen. to keep track of time even if the main power source is removed, the ds3231 has a backup …. It is fully compatible with arduino and has 5v input voltage. its i2c address could be 0x27 or 0x3f. you can get it for about $7 from bangood store. ds3231, i2c high precision real time clock module. ds3231 is a low cost, accurate i2c real time clock (rtc), with an integrated temperature compensated crystal oscillator (tcxo) and crystal. Step 4: setting the time and date in rtc. upload the below code to set time and date.uploading this code will load the time and date to rtc from your computer.after uploading the code open serial monitor to see the time and date. note. don't use latest version of arduino ide for programming.if you use latest arduino ide, you cannot set time and. Install lcd and rtc libraries. navigate to the libraries icon on the left bar of the arduino ide. search “liquidcrystal i2c”, then find the liquidcrystal i2c library by frank de brabander. click install button to install liquidcrystal i2c library. search “rtclib”, then find the rtc library by adafruit. this library works with both.
