Hey all, I just got my first Arduino (an Uno R3) a few days ago. I do Halloween props and I want to play a short sound effect and have a servo turn a clown head when a trigger is pressed. I've figured out the servo but this audio is driving me up a wall.
I bought an ISD1820 Sound Module with a little 8ohm speaker, since the dude at the store said that would be fine. I read the data sheet ( http://www.datasheetspdf.com/PDF/ISD1820/786127/1 ) and attached the VCC pin on the 1820 to the 3.3v pin on the Arduino, and the 1820's GND to Arduino's GND. I wired the speaker wires into the speaker holes on the 1820, then attempted to test it by using the push buttons.
I can tell it's getting power because if I push the REC button, the red LED lights up. But that's about all I can make it do. If I push FT to the other side, it'll make a bunch of clicking noises come out of the speaker, but it won't replay anything I say into the mic (like it's supposed to). If I try to record something by speaking into the mic while holding down the REC button, nothing happens when I try pushing PLAYE or PLAYL afterward. If I push the Repeat switch to the other side, the speaker just gives static followed five seconds or so later with a high-pitched tone.
There are two VCC pins and two GND pins on the 1820, and I tried using the VCC/GND on the left and then the VCC/GND on the right, and the unit does exactly the same thing either way.
I haven't even made it as far as making a sketch, because from what I understand you're supposed to be able to control record and playback via the buttons on the 1820, it doesn't HAVE to be controlled via the Arduino.
I don't know what's wrong and there's so many different possibilities, I don't know where to start. If it's the speaker, is there a different way for me to test if the speaker's okay? Could it be the mic on the 1820? Or the 1820 itself? Or am I doing something wrong?
