  • Is it possible to use one of these to drive a common anode Display module, like the 1.0" Single Digit Alphanumeric Display? If sow, how would you wire up a pair of these to drive that unit? Sorry a little lost on what I should use to avoid having to have a ton of resistors. I plan to multiplex the display to void to much draw. Or does that make sense?

  • Great tutorial, I a had no idea the USB tried to cover so many devices.

    I do have a question, and feel free to correct me if I am wrong on this. Is there an advantage in using an Arduino UNO for this when the Arduino Leonardo has core libraries to allow it to appear as a native Mouse and/or Keyboard?

  • I bet I'll get slapped for this, but I'll ask anyway. I am looking for suggestions on what power regulator I should use for this little guy when powering it from a 9v battery? I was thinking of using a Low Dropout Regulator 5 Volt 0.05A 3-Pin TO-92 Box from Jamco but I dont know if that little package will provide the correct output ourrent.

  • Never mind, I just replaced all the 'Wire.send' and 'Wire.receive' with the new Wire.h commands.

    For those who need it, replace all: 'Wire.send' with 'Wire.write' and 'Wire.receive' with ''

    Also is it common to have to add the byte() command when sending a 0x00 via Wire.write()? I find it kinda' odd when 0x02 works in the line above it in the example code. Must be some type value translation issue I would guess.

    • Dewclaws.. A true ditz'
  • is there a version of this example code in Arduino 1.0?

No public wish lists :(
