I was about to finish the circuit only to realize that the required board is an Arduino Due and I have the Uno. Because the Uno does not have its own DAC port, I was wondering what other options are available for me to accomplish the same thing while keeping the circuit as similar to the one listed in the tutorial. Thanks If you set the analogWriteResolution() value to a value higher than your board’s capabilities, the Arduino will discard the extra bits. For example: using the Due with analogWriteResolution(16) on a 12-bit DAC pin, only the first 12 bits of the values passed to analogWrite() will be used and the last 4 bits will be discarded.
