Real-Time Clock (RTC) on Arduino UNO R4 Minima

This video tutorial explains how to use the internal real-time clock (RTC) on an Arduino Uno R4 Minima to display the current date and time on an LCD screen. It covers the setup of the RTC and LCD libraries, setting the initial time and date, and using the loop function to display time. The tutorial also discusses controlling events based on time and the limitations of the R4 Minima's RTC, such as the lack of battery backup. The video concludes with a summary of key points and considerations for using the RTC effectively.

What are the potential issues with resetting the time in the setup function every time the Arduino powers up?

Explain how to format the time display to show 12-hour format instead of 24-hour format.

What is the role of the delay function in the loop when checking for specific time conditions?

Summarize the main points covered in the video regarding the use of the real time clock on the Arduino Uno R4.
