DS1307 Real Time Clock Module for Controlling Stepper and Relay

Projects General Guidance
1

Hi everyone, I've been working on this for the past few days. I have successfully run both my stepper and 8 relay module but cant figure out how to integrate the real time clock into my project.
The goal is to have the arduino run the stepper motor signal every 12 hours. The stepper motor will act as an automated fish feeder for when Im on holiday. I also want the arduino to switch on certain relays for the light etc.
Is the RTC necessary?

My problems are:

1) when I plug in the real time clock my arduino stops flashing and appears to be off. The arduino program apparently still recognized the arduino on com4.

2) When I ran the set time file in the DS1307RTC library it did pop up on the sketch but I couldn't run it because the following error was found:

also the serial monitor was not showing me anything.

Programming the RTC:

How to hook it up:
Solder wires to Gnd, Vcc, Sda, and Scl. Gnd should connect to ground, Vcc should connect to the Arduino's built in 5V supply, Sda should connect to A4 (analog pin 4), and Scl should connect to A5 (analog pin 5).
You need to run a program to set the time on the RTC to initialize it. I used the DS1307RTC library and the Time library to program my DS1307."The How to hook it up:

You need to verify that the I2C addresses of your RTC module, and any other I2C devices are unique.

This may be your best next step.

helpful when troubleshooting RTC issues.
