Light for life: Glowing button cycling jacket

Step 8 More on connecting the bits and pieces

To make it easier(or more difficult), I have soldiered all the electronics, the Arduino and its 5v battery, to a copper circuit-board. The circuit-board has a connector soldiered to it. The opposite connector is placed on the jacket, with each thread connected on a seperate pin. The connector is a 34-pin floppy connector I found in an old computer, and is perfect for my project.

It is also possible to sew the Arduino Lilypad and its batterypack directly to jacket. The board should be waterproof, are we to believe the creator Leah Buechley. Check out her webpage for more info.

All the ground(-) theads are put together. Remember where you place the - on the connector, as it has to be placed at the same place on Arduino board. As the Arduino Lilypad only has 14 seperate programmable connections, I have connected the light on the front of the jacket to the + on the battery. The 12 light and the 2 pushbuttons are put on the programmable connections.

On the programming part, I have basically borrowed Leah Buechley's code for her cycling-jacket, and given some more fancy light sequences, as I am very novice in Arduino programming. At the bottom of this page i have pasted in my code. Check out Leah's homepage for more detailed info on how to connect the electronic components together, particularly her jacket!

To insulate the conductive thread is advisable. This helps the threads touching eachother. Paint all the threads with puffy textile paint.
