    Hiya,
    I have build the clock and it is a great succes.
    Now i would like to change and upload the code on the atmega but my converter is different from the adafruit friend converter.
    The question is how do i connect the pins to the board.
    The pins on the converter are: dtr / rxd /txd /+5V /GND /3V3
    Hopefully you guys can help me out.
    Best regards,
    Sander

    The Defusable clock uses the standard pinout: RTS, RX, TX, 5V, NC, GND
    RTS and DTR are compatible. NC means “not connected”. RTS is on side marked “GRN” and ground is on side marked “BLK”. Green and black are the standard colors on FTDI cables.

    But if i understand correctly i dont need to connect the 3V3. Or do i connect the 3V3 to the NC of the board?

    You do not need to connect anything to the NC connection. That pin is unconnected.

    Thanx a lot,and now when i read back it was a silly question, no connect means no connect lol. i Just changed the code for the random wires and now its time to upload it.
    Thanks again for your time and effort.

    EDIT: it worked like a charm, now its time to insert the switches and make a nice video of it. And again thanks for your help.
