Traces of Touch

serendipity into the oblivion

Touch tests

with one comment

Today I have been testing my newly acquired QT1106 touch sensor. I decided to buy it from Rachels Electronics which turned out be a very good experience. Some times this very small shops has this extra nice customer service and this time I managed to get a special shipping option that fitted my needs and perfect packaging and of course a very good IC.

I decided to just connect the IC by itself and some leds as output together with the arduino terminal and after some thinkering with the code to get the calibration correct and to set it up in “wheel mode” I had a  nice test bench. The QT1106 has some nice features that it can  modify its resolution between 4 steps to 256 steps so I decided to implement some of those functions together with an autocalibration to get it working nicely and to faster iterate. Below you can see my steps I took putting it together and a small video of it working and you can also download the arduino code here.

  1. Great video! Nice to see the progress. Maybe make the photos smaller next time. :) What kind of form will house the electronics? What are your plans for the device?
