“Digital Clock with Hour/ Minute/Second Display, Alarm and Hour chime using Arduino Nano and RTC DS3231.
Iam a first time user of Arduino, and I actually made this project to learn programming of micro controllers. Though several digital clocks projects are seen online most of them are not having all features like seconds display, hour chime, alarm etc. Also in most of the clock projects the Alarm set time goes off when disconnected from the supply. I have incorporated all these features in my project, and I think its worth to share it with the community. Apart from Arduino Nano and DS 3231 RTC, all the other components were taken from scrap circuit boards. The success of this project, make me explore more complex projects using micro controllers.”
