    Arduino – Software Foundations 

    Learning   Examples | Foundations | Hacking | Links


    This page contains explanations of some of the elements of the Arduino hardware and software and the concepts behind them.


    • Sketch: The various components of a sketch and how they work.


    • Digital Pins: How the pins work and what it means for them to be configured as inputs or outputs.
    • Analog Input Pins: Details about the analog-to-digital conversion and other uses of the pins.
    • PWM: How the analogWrite() function simulates an analog output using pulse-width modulation.
    • Memory: The various types of memory available on the Arduino board.

    Five days later, can’t get data from arduino 

    Hey  guys, I am going insane and could really use help!

    I’m using a little omnidirectional mic as my “sensor” and am trying to throw these readings into a spreadsheet.

    The arduino printouts show “meaningful” values. As in, I get a value that makes sense; if it’s quiet, it’s one number, and if I make noise, the number goes up.

    However, when it gets to processing, I get this pattern of numbers that just repeats, regardless of what goes on and numbers that don’t match Arduino. Is this because of the kinds of packets of info I am getting from Arduino? I’m going CRAZY!


    Please help if yall have any ideas!

      Hi Bree,
      I am just using the Xbees them selves without Arduinos. I recommend you do the same, it is just easier if you are not trying to create a crazy complicated system.

      -Configure your Xbees as its shown in the 5th chapter.(API mode)
      -I think you might have to enter ATD03 instead of ATD02 because your sensor will not be a digital input.
      -When building the circuit use a piezo instead of a temp sensor cause it has a transducer and it will pick up sound as you are trying to do.
      -Use the processing sketch given for reading temperature, tweak it so that it will draw what you want to visualize. You can simply use the “temp” value in the sketch
      as the input for your visualizer.
      -Enjoy the awesomeness of your project!:)
