In order to create sound the voltage must be AC coupled. The missing piece is glaringly obvious we still need to throw a speaker on there! You might be tempted to just attach the speaker to the VOUT pin of the AD5330, but unfortunately that won't cut it. The whole point of the project, though, is to play some music. Now that the microSD shield is wired up to the AD5330 breakout board we're almost finished. Trust me, it's better to just double check the wiring now and make sure you've wired the project up properly. Debugging the entire project then becomes an exercise in frustration. With this many wires it's very easy to misplace one or two of them if that happens the whole circuit may not work once you upload some code. For each connection plug a jumper wire from the female header on the microSD shield to row on the breadboard that aligns with the specified pin name.ĭouble check all of your wiring. The table below shows the pins that need to be connected. You'll need 17 jumper wires to wire everything from the microSD shield to the AD5330 breakout board. Things get a little messy here so use care while wiring all of these signals. Make sure that the male ends are pointing down away from the components on the shield.ĪD5330 Breakout Installed in a BreadboardĪlright, with those two things taken care of we can get to wiring the project up. Start by soldering the 6 and 8 pin stackable headers onto the shield. Connecting all the pieces won't be very hard, but it will take some soldering! So what all do we need to do? Well for starters the microSD shield needs to go on top of the Arduino. Geez that's a whole lot of stuff we've got.

After connecting all of the pieces together we'll look at some code to get WAV files playing from the SD card.ĪD5330 Arduino Library with tutorial examples (GitHub)

In this tutorial we'll cover how to attach the microSD shield to the Arduino platform, and how to connect the AD5330 breakout board to the shield. By creating different voltages on a set frequency we can create sound! By using an Arduino with the DAC we will be able to create 256 distinct voltages between 0 and 3.3V by providing 8 bits via digital output pins on the Arduino. Remember, an 8 bit value can be any number between 0 and 255. An 8-bit DAC means that the DAC has 8 pins on which to set the digital value. Basically a DAC takes a digital value (think 1's and 0's) supplied by a microcontroller and turns it into a corresponding analog voltage. This means we'll also add the microSD shield to the project.Ī DAC is a Digital to Analog Converter. WAV files are uncompressed and the Arduino doesn't have too much internal ROM so we'll have to store the WAV files on an SD card. We're going to build it with an Arduino and the AD5330 breakout board, an 8-bit DAC. We're going to make a WAV player! (If you're not familiar, a WAV is an uncompressed audio file).
