Randomized Arduino Drum Machine
I like drum machines. However they are not always the easiest to build. I wanted one that is:
A. Simple, Yet Powerful - If it uses lots of components then it is too complicated
B. Sound - It's not much of a drum machine if it "beeps"
C. Easily Modifiable - If I can't change stuff for improvement, then it is kind of annoying.
A meticulous internet search wasn't so successful.
Finally, I found this but, even that was a bit un-editable although it was cool. I thought that the samples were a bit small and I for one was not going to rewrite a bunch of samples.
Therefore, I decided to play around with the code and rewrote my own version of it and tweaked it around until I got a sound I liked.
Remember: Make sure you have the Potentiometer on Analog Pin 1 and not Analog Pin Zero. The True Random library uses this wobbly voltage to pick random numbers.
I drew up a schematic from the code and then made it real.
I know this uses the TX (Digital Pin 1) and RX (Digital Pin Zero) but I had already built a Digital to Analog Converter shield for those pins and decided not to build it again.
Parts and Stuff.

Okay...So What Exactly Is a DAC?
A DAC or, Digital to Analog Converter is essentially, a device that takes a series of on-off pulses from a computer, which speaks in binary (or microcontroller) and then converts it into specific voltage levels.
So How does it do it exactly?
Collin Cunningham will explain in more depth:
So How does it do it exactly?
Collin Cunningham will explain in more depth:
Let's Get Started!
Build according to the schematic. I can supply pictures of my build in the end but my camera was broken at the time I made this and so, I don't have the pictures for during the build. Sorry.
Let's Finish!
Solder the headers terminal and the output wires and commence testing. (make sure you screw in the potentiometer.)
Done!
That's it!
