Later I connected them with accelerometer (3 analog pins; x,y and z).     It is always good to check serial monitor or printed values to see if values are stable […]]]> http://nerding.at/course/101/?feed=rss2&p=1678 0 http://nerding.at/course/101/?p=1654 http://nerding.at/course/101/?p=1654#comments Fri, 11 Jul 2014 11:34:55 +0000 http://nerding.at/course/101/?p=1654 MORE DRAWING APPLICATION I was exploring drawing (processing code) with accelerometer: 1 – DRAWING PATTERNS WITH ELLIPSES ellipse_     The size of ellipses is changing accordingly to speed of body motion. With fast motion ellipses are bigger and cover hole canvas –   they are applying new canvas for drawing (some kind of “reset”) […]]]> http://nerding.at/course/101/?feed=rss2&p=1654 0 http://nerding.at/course/101/?p=1641 http://nerding.at/course/101/?p=1641#comments Fri, 11 Jul 2014 11:07:39 +0000 http://nerding.at/course/101/?p=1641 GYROSCOPE  Gyro L3G4200D detects or measure rotation on 3 axis: x, y and z. It has three selectable scales: 250 , 500 or 2000 deg/sec. Gyros are not affected by gravity (like accelerometers) and can give you exact information how object is orientated. Gyros and accelerometers are often used together because of great complement to […]]]> http://nerding.at/course/101/?feed=rss2&p=1641 0 http://nerding.at/course/101/?p=1522 http://nerding.at/course/101/?p=1522#comments Sun, 29 Jun 2014 21:30:17 +0000 http://nerding.at/course/101/?p=1522 CUSTOM MADE TEXTILE PRESSURE AND BEND SENSOR Custom made pressure and bend textile sensors I connected to the same drawing application.

I decided to work with bend sensors, custom made textile sensors, potentiometers, accelerometer and gyro.
