Small hourly beep charm Answered
I want to make a very small charm that will play a short beep sequence alarm every hour. It does not need a stop button for the alarm, just beep a few times then be silent for another hour. I'm thinking attiny, speaker, battery. Or something along those lines. Or is this simpler with a 555 (I've never used one before)? I have used attiny for lights, but never anything with sound. Can anybody point me in the right direction for code and also a good place to buy tiny inexpensive speakers? Thanks so much!
