  • Hi guys - can I power the JPEG trigger by connecting the 1-5V pin to my Arduino Uno +5V? Or should I use a separate source...

    Also - I'm confused by the trigger pins, say for D2, do I need to hook up the 5V and GND or just the trigger pin?


  • I just did a test - I set pin 10 to an output at the start, and run... after this line of code:

    if(!sd.begin(SD_SEL, SPI_HALF_SPEED)) sd.initErrorHalt();

    I do a digitalRead() on pin 10 and it's 1. I'm wondering if it's ok for me to set to LOW at that point and use it for my own use?

  • Thanks Toni I'm using Bill's library so I thought it took care of that 9 vs.10 issue. I'll go to his site and ask him what's up.

  • Looking at the schematic it seems that pin 10 is free but when I connect it to an LED, the LED lights up.I'm using an UNO. Pin 5 seems to work as a free pin but I'm confused as to what other pins are actually free to use.

No public wish lists :(
