eTextile Multi-Touchpad Playing Synth

190630 - Multi-Touchpad Playing Synth !

The intention behind the research and development of a multi-touchpad is to see if it is a good sensor to integrate with a Body Suit.

I was able to generate sounds by touching / tapping / pressing each one of the touchpads.

View images below to see how the Paper Touchpad was made.

Tools: Arduino & openFrameworks

Challenge: Drum sounds created noise whereas the synth wav worked beautifully.

Fixed ! with an ‘if’ statement in openFrameworks, saying that ‘if the value is smaller then the current threshold && bigger then the previous && the current file is loaded, do not play !

I learned how to make this multi-touch sensor from attending workshop by  KOBAKANT and vvvv.


The images below show how the etextile piece was made.


The images below show how the paper & copper prototype was made.

voltage divider

Voltage Divider - Bend Sensor controls LEDs

190317 - Voltage Divider > Sensor to control LEDs

The player above has 2 videos:

They show the tests of the bend sensor affecting the red led.

The first video uses a Flora board by adafruit.

In the second one, I am testing the ATtiny85 which ended up being the chosen microcontroller.


The sketchbook notes shows how the Voltage Divider works.

It ables me to turn the ohm changes from the sensor into voltage for analog reading by the microcontroller.
