Hello (Make Your Own) Arduino

For reasons I haven’t uncovered yet, I was unable to use the Arduino IDE to burn the bootloader to a fabbed Arduino board. For my first attempt at this, see the Fabkit / Fabduino post. Also see Ed Baafi’s Fabkit / Fabduino page for how to program an fabbed Arduino without an external clock through the Arduino IDE. In both OS X and Ubuntu I was unable to connect to the board through the IDE. Shawn Wallace suggested that I use the following code. (See “To Program Your Arduino” section below) The code below worked for me in Ubuntu. NOTE: This code below works for a using an external 8MHZ resonator, see the links to the .png files.

To Program Your Arduino:

Set the fuses with:

Paste code is all in one line

avrdude -c usbtiny -p m168 -B 5 -u -U lock:w:0x0F:m -U  efuse:w:0x00:m -U
hfuse:w:0xdd:m -U lfuse:w:0xf6:m -P usb

Burn the bootloader with:

Paste code is all in one line

avrdude -P usb -c usbtiny -p m168  -u -U flash:w:ATmegaBOOT_168_pro_8MHz.hex
-U lock:w:0x0F:m -B .2

The options used:

-u –> Disable safemode, default when running from a script.
-U :r|w|v:[:format] –> Memory operation specification. Multiple -U options are allowed, each request is performed in the order specified.

Hello Stepper Motor

This board is a “hello world” for running a basic stepper motor board.. To make it yourself – download the Fab Academy board diagrams / .pngs and code.

To Program the Board / Motor to Do a Half Turn

sudo make -f hello.stepper.44.half.make program-usbtiny

To Program the Board / Motor to Do a Full Turn

sudo make -f hello.stepper.44.full.make program-usbtiny

To Program the Board / Motor to Do a Wave

sudo make -f hello.stepper.44.wave.make program-usbtiny

I had trouble getting this board to work at first, the motor would turn back and forth only a small amount, not the full or half turn that the program specified. Then I checked the jumper wires. One of the wires was bad (the header was not connected). After replacing the faulty wire, the motor ran.

Hello RGB

This board is a “hello world” for a basic RGB LED. The program flashed to the microcontroller cycles through the available LED colors. To make it yourself – download the Fab Academy board diagrams / pngs and code.

Hello LED Matrix

This board is a “hello world” for a basic LED matrix. I labeled some green LEDs as red by accident, so there are green and red LEDs on the board. (I had intended them to be all red). Download the Fab Academy board diagrams / pngs and code.
