Intro: Blinky FishAssembly instructions for an add-on board for the Arduino.

Ithas some LED's and a button.

It connects to digital pins 9-13 and ground. My hope is that this will be useful to people that want to play with writing code for the Arduino, but don't want to build a littlcircuit every time they want to test something out.

I'm including all the files you would need to build your own. I am also offering these for sale. I figure this is the only real way to find out if this is useful to other people

I have only a few boards right now, but they are not quite right. I have included a hack towards the end of this instructable.

Here is a small web-store I've set-up. The name is stupid, but easy to remember and spell.

step 1:PartsHere are the parts!

-PCB --3 - LED's-Resistors-Push button-Right angle header

step 2:ToolsTools -

-Solder-Soldering iron

-Cutters (?)

-The soldering is pretty easy, so I never had to use the flux pen.

- To make anything happen, you will also need an Arduiono 2009 and a computer with the Arduino IDE.

- I like to work on a white peice of paper, it keeps me from loosing parts. It is also a good if you are taking photos.

step 4:Build - LED'sNow put on the LED's

LED's are one way, the short lead is negative. This side of the LED is usually flat or notched or something like that. On the PCB the flat side of the circle is for thenegative lead.

The soldering is the same.


6/12


step 5:Build - ButtonThe botton only fits in one way (I think).

You can just pop it in and solder. The leads are sort of springy and bent, so that they stay in place nicely while you solder.

Now isn't that clever!


7/12


step 6:Build - HeaderThis is a right angle header. Straight headers are more typical. This is just like those, but bent at a 90deg angle.

Look at the picture below to see which way it goes.

It is a little tricky to hold the header in place while you solder, but you can do it!

If some of the hole are a little off center, then the header will stay in place nicely. Of course, the person designing the board would have to think of this ahead of time.so well, here we are.


8/12


step 7:HACK - cut a trace

Well, if you've got one of the first few boards then you need to hack a little to get everything to line up correctly withe the Arduino. ( I forgot about the resistor and LEDattached to pin 13 on the Arduino board).

You can cut the trace between the button and R1 with an exacto knife.

step 8:Hack - Add a wireThe next hack is to add a wire on the back of the board.

This goes from R1 to header pin 12.

digitalWrite(Led3, 0);delay(1000);digitalWrite(Led1, 1);digitalWrite(Led2, 1);digitalWrite(Led3, 1);delay(1000);

}}

step 11:Board LayoutI laid out the board using Eagle.

step 12:SchematicHere is the schematic for the board.

This is before the hack.

ADD HACKED SCHEMATIC


11/12


step 13:Design and Fabrication filesHere are all the files.

The *.brd and *.sch files can be opened and edited in Eagle.

The zipped files are the files you would send to get the board made. These are called "gerber files" (which means "the files you send to get the board made").

Gerber files are sort of like PDF's. They are hard to edit, but can be read by read by most people and won't get messed up when tranfered from program to program.

You can look at the gerbers in Eagle or with a gerber viewer such as VeiwMate (from Pentalogix (i think)). Each file shows one layer of the board.

These are:

-Top Overlay (also called SilkScreen) - this is the white graphics

-Top Layer (also called Primary copper) - this these are the traces that you can sort of see on the top side of the board.-Top Solder Mask - Circuit boards are acutally yellowish, they are painted green (or black or red or whatever) with a dielectric ink (insulator). This keeps the coppertraces insulated and keeps the solder from running all over when assembling the board. This file shows every where that the green stuff does not cover. That is, it shthe shiny silver parts.

-Bottom layer ( or Secondary copper) - shows the traces on the bottom of the board-Bottom Solder Mask - Shows the exposed copper on the bottom of the board.

-There is also a Mechanical layer which is the outline of the board. I suppose this is called "Mechanical" because it is cut with mechanical machine. Unlike the rest oflayers, which are etched, screened or whatever.

-- So that is that.

Once I fix these boards (so they don't need the cut and extra wires), I'll post the new files and order some new boards.

Thanks for looking!

-Marc

abbtech says: Aug 15, 2010. 2:44 PM REPCool lookin board!

w0rm5 says: Aug 13, 2010. 5:44 AM REPThat seemed cool till now, but whats the use of making something small and fun for kids if it has to be attached to an arduino board?

marc.cryan says: Aug 12, 2010. 10:14 AM REPI started a web page to sell stuff - it is www.PoopDirect.com

It needs some work, so if you have questions please send me a note.

I'm planning to update it quite a bit tonight.

Thanks!-Marc

joerice01 says: Aug 12, 2010. 6:55 PM REPNew domain name perhaps?

mikeasaurus says: Aug 12, 2010. 10:50 AM REPreminds me of this uy....

kelseymh says: Aug 11, 2010. 10:35 PM REPThis is excellent! Detailed, clear pictures, and the option of actually making it or letting you do the work :-) I only noticed one thing which needs fixing: OnStep 3, you tells that the resistors are all "##K" :-)

marc.cryan says: Aug 12, 2010. 10:12 AM REPThanks - done and done!
