Building an Arduino Shield



No, an Arduino shield is not something that will protect you from Arduinos.  Resistance IS futile! In the world of microcontrollers, "shields" are, in essence, PC boards with headers that allow you to stack them atop the main microcontroller board.  So instead of the digital rat's nest of wires that you see in my proto-board version of the DDS signal generator, we'll have the AD9850 board mounted above the Arduino on its shield.  But take heart, my fellow luddites:  I have left a lot of space on the board for the construction of a DISCRETE COMPONENT, ANALOG, NON-DIGITAL amplifier.  I'd like to get the output from the 9850 up to around 7 dbm.

  1. That looks like a pretty standard board. How did you deal with the funny width gap in the pin spacing?

  2. see http://www.adafruit.com/products/187

    It is a standard protoboard and headers, but they slightly bent the pins of one of the headers to make it fit.

    You could bend your own headers, or just buy a set of theirs for $6.00 (including board).
