I am very new to the Arduino world.
A friend of mine want a special alarm clock. He wants an alarm clock with 27 alarms of 3 seconds each with no LCD or anything else...only the arduino and the speaker. To set the arduino to start at 12 am when you plug it to a battery.
I made the program in C++ to have an idea of how it's going but i don't know how to implement on the Arduino.
It's possible this without using a 32.768kHz crystal and a DS1307?
Thank you and sorry for my english :)
