Hi
I bought the Piezo speaker from picaxe, however the sound generated was very quiet. I only have one PIN free on a 08M2. (Actually, I only have PIN 3 left, so big problems ,I guess?). I want to keep the electronics very simple due to space. I need the user of an LED light to know when the light is on or off as its on their head and used during the day((dont ask!!), and thought that a speaker would do the trick eg 1 one beep on, 2 beeps off.
The Piezo is to quiet and so I went a bought some fancy mini 10mm speakers from Farnell, http://uk.farnell.com/jsp/search/productdetail.jsp?SKU=1299880
They have turned up today and guess what, they are as quiet as the Piezo, so its not the Piezo at fault!
Can anyone help here, I just want two signals as I said as loud as an old casio watch alarm used to be in the 70s, however I don't have much space for Amps and only Pin 3 left.
Thanks for your help.
