Hi all,
I want to connect a very loud speaker with my arduino. The only thing that I intend to output is a Siren kind of sound as a warning only, hence no need to output music and stuff.
I was also looking for a typical PCB circular kind of speaker but then I found there are 4Ohms, 8Ohms ... and all these things which made me confused. Also there are many frwquency ranges... for example I know a human can hear from 20hz to 20Khz ... but I coulnd't find one...
My question is this.
1. How do you safely connect it to your arduino? (a typical micro controller)
2. What values should I be looking at to buy the speaker?
Thanks for your time
