The aim of this project is to design and develop a Medicine Reminder Alarm system using Arduino Uno, a DS3231 Real-Time Clock (RTC) module, and a 16x2 LCD display. This system intends to assist ...

Now we know how to set time in the module, let's use it with an LCD to make a simple clock. Material Required. Arduino Uno; DS1307 Module; LCD Display; I2C LCD Driver Module; After gathering the above ...

In the circuit diagram below, the SDA and SCL lines are connected to VCC through two 3.3kΩ pull-up resistors, R2 and R3. ... To interface with the DS1307 RTC module using I2C on an Arduino, you need ...

Fig. 1: Author’s prototype Fig. 2: Block diagram of the project Circuit and working. Circuit diagram of the Arduino real-time clock with temperature display is shown in Fig. 3. It is built around ...

The receiver includes 433MHz ASK RF receiver module, real-time clock (RTC) module, and Arduino Nano. Both sensor nodes transmit data of sensed ... (total eight values) and gives them to computer, ...

DS3231 RTC Module Schematic and Circuit Connections. The circuit diagram to connect the RTC3231 to the ESP board is given below: The RTC DS3231 IC uses the I2C mode of communication. It has SCL, SDA, ...
