9. E-Textiles and Wearables II#
This week little ATtiny and I became friends. A small marvelous device to experiment with wearables and to try first ideas.
My weekly assingment is to create a swatch using an ATtiny with one input and one output and to create 2 actuator swatches.
Experimenting with optical fibers is of particular interest to me this week. I am fascinated by the unbelievable effects that can result from the sideways emitting fibers. Combining the whole thing with the super-small ATtiny allows so many possibilities to integrate optical fibers into textiles.
The biggest challenge this week was programming the ATtiny

Next I plugged the circuit with LED and a resistor on the breadboard. In the following picture you can see which pins I used.
Arduino as programmer#
First I loaded a sketch onto the Arduino Uno to make it a programmer. For this we open the Sketch under “File” -> “Examples” ->”11.ArduinoISP” -> “ArduinoISP” and transfer it as usual via USB to our Uno. Now it is ready and can program further chips.
Then I created the sketch for the blinking LED.
Now I have loaded the sketch onto the ATtiny.
-
Select “Tools” in the Arduino IDE.
-
There we have to select the “Board” first. Here “Tiny” must be entered.
-
As “Processor” select “ATtiny85
-
Select as “Clock “1 Mhz (internal)
-
Select “Arduino as ISP” as “Programmer
Now the sketch can be transferred to the ATtiny85.
Actuator 1 LED#
Actuator 2 Optical Fiber#
In these two short videos you can see how I connected the ATtiny and optical fibers. These optical fibers were intended for an end-to-end application. By scratching the tube with a cutter knife, a laterally emitting optical fiber could be produced.

This can result in fantastic application-related textile projects. And I look forward to being able to test it all out soon!!!
The application of optical fibers in textiles will be realized in my final project. I am looking forward to the exciting experiments and illuminating results :)
