190524 - Bend Sensor Read In Arduino and Visualized in openFrameworks

2 Bend Sensors being visualized.

Reading serial in oF via ofxSimpleSerial to read both separate inputs.

In Arduino, I’m using the INPUT_PULLUP in order to use the internal 20k ohm resistor as a voltage divider.

A0 + A1 as analog pins for both sensors and the other Ground pins for the other side with the alligator clips.

I learned about creating matrices during Make Your Own Multi-Touchpad Workshop.

We read the serial values using vvvv, a commercial toolkit for visual programming, as well as Processing, a JAVA based language.

Since openFrameworks is my tool of choice, I used it to write an app to visualize Multi-Touchpads.
