The timers can be made available with stopMozzi(), which stops audio interrupts, until you call startMozzi(). If you need analogWrite(), you can do PWM output on any digital pins using the technique in Mozzi>examples>11.Communication>Sinewave_PWM_pins_HIFI. In HIFI mode, Mozzi uses Timer1 (or Timer4 on some boards), and Timer2, so pins 3 and 11 are also out. In STANDARD and STANDARD_PLUS audio modes, Mozzi takes over Timer1 (pins 9 and 10), but you can use the Timer2 pins, 3 and 11 (your board may differ). Mozzi provides EventDelay() for scheduling instead of delay().ĪnalogRead() is replaced by mozziAnalogRead(), which works in the background instead of blocking the processor. While Mozzi is running, calling delay(), delayMicroseconds(), or other functions which wait or cycle through loops can cause audio glitches. Start or look up a topic on the users forum.Īlso, feel free to submit any issues on the GitHub Mozzi site. There is practical help on the learn page on the Mozzi site. There’s documentation in the extras/doc folder in the Mozzi download and online. There’s a detailed example explaining the different parts here. Here’s a template for an empty Mozzi sketch: #include // at the top of your sketch Uno, Nano, Pro Mini and other Atmega 328 based boardsįor more about audio output, including HIFI mode, read the Mozzi core module documentation. Try some examples from the File > Examples > Mozzi menu. Plug into your computer and listen with a sound program like Audacity. To hear Mozzi, wire a 3.5mm audio jack with the centre to the audio out pin for your Arduino as shown in the table below, and the shield to GND on the Arduino. Then, follow the instructions from the Arduino libraries guide.

Phase and amplitude modulation, with reverb: Ī chordal wash of detuned oscillator pairs: Here are some sounds of the example sketches which come with Mozzi: Performance, or make interactive sonifications of sensors, on a small, modular and super cheap Arduino, without the need for additional shields, message passing or external synths. You can use Mozzi to generate algorithmic music for an installation or These sounds can be quickly and easily constructed from familiar synthesis units like oscillators, delays, filters and envelopes. Your Arduino to life by allowing it to produce much more complex and interesting growls, sweeps and chorusing atmospherics. Second, by sending characters representing specific letters.Currently your Arduino can only beep like a microwave oven. It shows how to send morse code in two ways: first, by sending a string. There is an example sketch included with the Morse library, given below. See the Morse Code Beep Arduino Micro page for a simple circuit using the Arduino Micro to send out morse code beeps. Check with the manufacturer for information if it isn't indicated on the board itself. On the Arudino Micro and Arduino Leonardo, these pins are 3, 5, 9, 10, 11, and 13 (as listed here). But it means you have to make sure and use a PWM enabled pin. The Morse library uses PWM to send the sound signal through the speaker, which makes the sound less harsh and annoying. Make sure you pick a pin where pulse width modulation (PWM) is enabled. When using the Morse Library, you have to pick which pin you're using. When you re-open the Sketch > Include Library menu, you should see the library you added at the very bottom. Navigate to the zip file Morse.zip and pick it. Open the Arduino Development Environment, and pick Sketch > Include Library > Add. Now you can load the library into Arduino using the zip file you've just created. The folder Morse will contain a file called Morse.h Loading Library in Arduino Morse.zip will contain a folder called Morse/ To install the W5OBM Morse library, download the directory containing the C code for the Morse library ( link to the code).Ĭreate a zip file from this directory, which will be called Morse.zip
