 Bigger Bigger  Smaller Smaller  Reset Reset

Let me preface this by saying I'm very new to electronics. I have a bit of experience with programming, but nothing too low level.

So- I have an Arduino Due. I was able to successfully follow this instructable for getting audio into the Due- at least, I can read it in the serial monitor and it appears to be working.

But I'm really having trouble getting audio out. At this point what I'd really like to do is send a sine wave (or white noise, or whatever- any kind of audio) out of the DAC in the simplest way possible. I'm working towards using the audio I'm getting from the input, but I just want to take small steps to start.

So I guess my question is, how do I get signal from the DAC into speakers? What does that circuit look like?

Hello,
Just put the DAC1 output of your Due to the + of your amplifier, and the - to the ground. You can put a 500 Ohm resistor between DAC1 and amplifier to be sure not to harm your Arduino.
If you want to make a sine wave out, look at RC Arduino : http://rcarduino.blogspot.com/2012/12/arduino-due-dds-part-1-sinewaves-and.html

You can look too to my blog, to see how to make sounds with Due (synth, samples, etc...) :
