OUTPUT DEVICES - week11

This week I made a Fabduino, a Fabable Arduino Compatible Board . Fabduino was introduced by Ed Baari. My process this week is based on both Ed and Tiff's online tutorial on how to create a Fabduino board. You can download the Eagle board, schematic files, PNGs for the milling and other required file from this link. When you do the milling, you don't necessarily have to create the holes for the female headers. In my case, I soldered the female headers on top of the board. Make sure that you debur your board as soon as you finish the milling. Then clean the board with water after clearing the path using an exacto knife. Soldering the ATMega 168 can be a bit challenging but other parts are relatively easy.

Programming The Fabduino Using FabISP

Ed's website covers very well on how to initially program the Fabduino using the FabISP. First, make sure the boards.txt from the Fabkit.zip inside the sub-folder, "hardware" created inside the user's Arduino sketchbook folder (Mac OS X: Documents/Arduino/hardware/fabduino/boards.txt). Once the board.txt file is installed, restart the Arduino IDE. I connected all of the header, MISO, V, MOSI, SCK, GND, RST and ran my Arduino IDE. One mistake I made was forgetting to connect the RST from FabISP and Fabduino while programming my board. Just hold the wire on the RESET pin while you are programming the board. Then with both FabISP and and Fabduino connected to the computer, go to Arduino IDE's "Tools > Board" and pick the Fabduino w/168(Internal Clock) and then pick "Tools > Burn Bootloader" with "USBTinyISP" selected.

Using The Fabduino

Fabduino works pretty much the same way as the Arduino. I used potentiometer as an input to change the blinking frequency of a couple of IR LEDs. Here is a link where you can obtain the Arduino example code. You can see the result below:
