This last week, I purchased this kit:
In the kit is an 8ohm speaker with leads. Since the kit comes with absolutely no instructions, I ended up trying this example: http://arduino.cc/en/Tutorial/Tone.
It sorta works, but the speaker is so quiet it's really hard to hear what tone is playing. I've googled around and found that even with a 100ohm resistor, that speaker is probably pulling enough power to burn out my arduino pin, and that if I want any more volume, I'll need a "simple" amplifier (which, as it turns out, isn't so simple for someone as new as I am).
I guess I just have a hard time believing the kit would include a speaker, but would not also provide means to use it correctly.
What am I missing here?
