I'm trying to implement audio output using R2R 8bit DAC and Arduino UNO.
This is my hardware:

This is the sound i want to hear:

This is a wav file, 16Khz, mono, 8 bit pcm.
I used matlab to retrieve the binary data from the wav file, and then wrote this code:

I connected the output to some speaker and what i hear is some strange sound..do you think i miss something in my hardware/software?
Thanks!
