    agreed. im using the A0-A5 on a pro mini, using PORTC calls for parallel data output on the entire PORTC. very time/cycles sensitive. i would love to have all six pins available.

    other than that, this looks interesting!

    What is the purpose of the resistors on D0 and D1 (RX and TX)? These are only on the Pros, and not on the regular Arduinos or the Pro Minis. I have had to remove and jumper them on previous projects. Thanks.

    I used your your code for debounce and its working great.

    The solution i posted above from 2010 worked but added too much delay and tended to get annoying when trying to push a button a bunch of times quick. i have removed it and im now using yours.

    all better.

    Im using this board with an Arduino Pro 5V (DEV-09219).
    In order to get it to work with the Arduino Pro I had to bypass the 1k resistors on the RX and TX lines (D0 and D1) on the Arduino Pro. Im not sure why the resistors are in-line to pins D0 and D1, because they are not in the Regular Arduinos, nor are they on the Pro Minis.
    It worked perfect with my Uno and my Duemilanove.
    Im mentioning it to save some other sucker a few hours of troubleshooting. UGH.

    1. has anyone used one of these as a simple vibration sensor? i need a CHEAP and small sensor to detect movement.
    2. will the internal balls and pins get broken or damaged if this is installed in a dynamic environment? Im talking in dancing shoes…
      I am making adult light up shoes using an attiny and some leds. My gf insists that there has to be a switch of some kind in the circuit and cant be always on. thx.

    what did you replace the 1M resistor with? Im using this mic with a msgeq7 chip and have too much gain. im hitting the full 5 volts. the msgeq7 is 20db on its own and thats how much id like to reduce. thanks.

    To answer my own question. I was able to change the address on the FOB so that I can have two projects operated by two separate FOBs in close proximity. <br />
    <br />
    Using the AVR Studio, and a SFE pocket AVR programmer: I updated the FOB firmware, modifying the four data_array[x] values from 0xE7 to something else. I did this in the file called nordic-nRF24L01.c. Then loaded into the FOB.<br />
    <br />

    can anyone comment on changing the address of these things? I want to have several art projects operating in close proximity, controlled with multiple FOBs.<br />
    <br />
    i thought i read somewhere that the four data_array[x] bytes contain the address but cant find the specifics anywhere. im looking in the nRF24L01+ datasheet right now.<br />
    <br />
    which of the four 0xE7 should I change? and to what?<br />
    <br />
    thanks.<br />

    i shoulda pressed preview…

    include util/delay.h

    with angle brackets where they go…

    if you the actual firmware let me know. otherwise, theres also a solution in the SFE forums, so search for:
    “Debouncing the Nordic FOB"
    I added the line:


    and then after this line:
    sbi(PORTB, TX_CSN); //Deselect chip
    I added one of these:
    and its been working perfect for my needs.
    I used the AVR Studio to edit/compile the code and uploaded the firmware to the FOB with a SFE pocket programmer.

No public wish lists :(
