  • Getting wildly intermittent results. Sometimes it works sometimes it doesn’t. Tried it wired to the Arduino 5V as in this diagram http://www.allenpitts.com/pir_Sensor.gif And substituted a 9V battery to the sensor. Neither reliable. Would hate to have the security of my home or business reliant on this system.

    Also the instructions above say: ‘Note: The colors of the wires can vary greatly. Looking at the unit from the top, the middle wire is ground, the left-most wire is the alarm, and the right-most is the power.’ This is unspecific. ‘From the top’ with the wire output at the bottom or ‘From the top’ with the wire output on the top. One has a fifty-fifty chance above a reversed hook up and a puff smoke.

  • Could you drive two SparkFun Mono Audio Amp Breakout - TPA2005D1 with the MP3 Player shield and the Arduino Uno to get stereo?

  • Hello Sparkfun,

    I am new to Arduino. I understand DC circuits, Ohm’s law, parallel and serial circuits, digital multi meter use and basic soldering skills.

    Many electronic kits have been built from Chaney and Velleman and Ramsey mostly related to LED sequencing and displays.

    As a result an interest has been developed in 1. Activating devices using sensors like the Parallax PIR sensor http://www.parallax.com/product/555-28027?SortField=ProductName,ProductName

    1. Activating sound devices that play MP3 or other stereo audio from SD or Micro SD cards or USB flash drives with PIR sensors.

    2. Activating complex LED diplays with PIR sensors.

    So I am going to purchase a board to get my feet wet with Arduino systems and programming.

    So my question is: Should I start with the UNO or the Red Board (or other?)
    While I am not a rich man the five dollar difference in price is not an issue. One difference I see is the the RedBoard uses a mini-B USB connector whule the UNO uses a mini-USB connector But do not both types have a standard USB connector at the other end? http://www.amazon.com/AmazonBasics–Male–Female-Extension-Cable/dp/B001TH7GV4/ref=lp_464394_1_10?s=pc&ie=UTF8&qid=1416848508&sr=1-10 If so, then this is not an issue for me either.

    The real issue is one or the other easier for a beginner?

    Thanks.

  • Hello Sparkfun forum.

    I am very new to the whole Arduino thing so forgive me if I ask basic questions.

    The plan is to use the SparkFun MP3 Player Shield https://www.sparkfun.com/categories/273 to play an mp3 file. The SparkFun MP3 Player Shield would be activated by a PIR sensor http://www.parallax.com/product/555-28027?SortField=ProductName,ProductName The MP3 files would be input to a Micro SD file card from a PC. The SparkFun MP3 Player Shield would out put to a stereo amplifier SparkFun Audio Amplifier Kit - STA540. The SparkFun Audio Amplifier Kit would output to a pair of 8 Ohm speakers

    Is this a configurations that will work?

    Is any programming required for the SparkFun MP3 Player Shield?

    Thanks.
