May 23, 2022 · These EEPROM chips use the I2C interface to connect with microcontrollers like Arduino. Jumper wire for connecting the parts 9. Arduino Uno DS1302 Real Time Clock Module LCD with I2C interface Connecting the Components Connect the components to the Arduino Uno. Time and date are displayed on 1602 LCD and it can be set with 2 buttons. 5v GND --> GND #include <ThreeWire. It is a simple clock with LCD display, an RTC (real time clock) and 3 buttons . Aug 12, 2021 · As mentioned in the comments: Your LCD and the RTC both use the I2C bus for communication. So here is the coding without adding a LCD I2C code yet. I'm using the ATMega168A-PU. As a result, it uses the same I2C bus as the DS1307. Jan 15, 2022 · The precision and time backup is the main reason which makes the use of RTC a necessity compared to using the internal timer of a microcontroller. Mar 17, 2024 · This is an Arduino Clock, using a 16x2 I2C LCD Display and an RTC DS1302 Dec 27, 2024 · Learn to use the DS1302 RTC module with Arduino and I2C LCD. I have both the devices connected to the scl and sda line, sharing it. 6. Arduino time and date. Mar 8, 2022 · Microcontroller 8051: Interfacing Real Time Clock (DS1307) using I2C with AT89S52 Microcontroller Interfacing Real Time Clock (DS1307) with Arduino Controller in Proteus Software The RTC DS1307 serial real-time clock (RTC AT24C32 EEPROM) is a low power, full binary-coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM. This circuit features an Arduino UNO microcontroller that manages a servo motor and communicates with an RTC (Real-Time Clock) module and a 16x2 I2C LCD display.
