Hello everyone, in this project we’ll try to make an easy alarm clock with Arduino UNO board, this project is a mix of different modules that I used before, if you’re stuck on something you can check in the website for the module tutorial, because that’s how I usually work: Do things separately and then start mixing :D.
For this project we will need:
Arduino UNO Board, or you can use what suits you:
DS1302 RTC module:
4*4 Matrix Keypad module:
LCD i2c screen:
Buzzer module, or the 2 pins buzzer:
In case you’re stuck on something you can check these previous tutorials about the modules above:
Libraries and Code:
LCD i2c library You can chose this or download your own
Keypad library Or you can download it from Arduino IDE
Code functionning is pretty simple, after wiring the module you can press “*” to set the time and date on the DS1302 RTC, the display will show then the current day and time if you want to set the alarm you press “A” and you can set which hour and minute, and you can deactivate it by pressing “B” before time or pressing any button while ringing.
I hope you like it, any problem you can contact me.
