Building the Auduino Synthesiser (Arduino Based DIY Synth)

It is so easy to forget a wire or two. I find a useful discipline is to draw out the circuit diagram then use a coloured pen to mark each wire on the diagram as you solder it in place. Also ... I don't think this makes it easier or more reliable but I really like to use ribon cable instead of a rat's nest of individual wires, especially when connecting between parts on the lid and parts in the box, it just looks a lot more satisfying.

Hi! Great project. Are you using the same code as this?: https://github.com/JoshuaACNewman/Auduino2 Looking at the code it seems it generates a single wave but you explain that your project uses two triangular waves. Is it a different code? If so, could you share that code? Thanks!
