Summary of the Circuit

This circuit integrates an Arduino UNO microcontroller with a Servo motor and a DS1307 Real-Time Clock (RTC) module. The Arduino UNO serves as the central processing unit, controlling the Servo motor's position and maintaining accurate timekeeping with the DS1307 RTC. The Servo motor is powered and controlled by the Arduino, while the RTC module communicates with the Arduino over the I2C protocol using the SDA and SCL lines.

Component List

Arduino UNO

• Description: A microcontroller board based on the ATmega328P.
• Purpose: Acts as the central controller for the circuit, interfacing with the Servo motor and the DS1307 RTC module.
• Pins: UNUSED, IOREF, Reset, 3.3V, 5V, GND, Vin, A0-A5, SCL, SDA, AREF, D0-D13.

Servo (Wokwi Compatible)

• Description: A motor capable of precise angular positioning.
• Purpose: Receives PWM signals from the Arduino to adjust its position.
• Pins: GND, V+, PWM.

DS1307 RTC (Wokwi Compatible)

• Description: A low-power, full binary-coded decimal (BCD) clock/calendar with 56 bytes of NV SRAM.
• Purpose: Keeps track of the current time even when the Arduino is powered off.
• Pins: GND, 5V, SDA, SCL, SQW.
