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
Impressions/ Useful links#
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 :)
