Fun With Touch Sensors
Saturday, April 17, 2010 from 1:00 PM to 3:00 PM (EDT)
Brooklyn, United States
Want to build an awesome touch-controlled super gadget? Come join Joel Murphy of www.rachelselectronics.com in a workshop on interfacing with capacitve touch sensors. You'll build an interface to the QT-1106 sensor chip, hook it up to an Arduino, and use it to read finger positions on foil sensors. This sensor allows for up to 7 touch keys, plus a continuous sensor strip, and allows for making interfaces like the original iPod.
Joel will provide the interface boards and hardware. You bring laptop and Arduino board. In additional to learning about capacitive sensor technology, Joel will cover the SPI interface used to talk to this chip (as well as many others), and provide hands-on instruction on how to pull this all together.
Every student gets a kit with a QT1106 Breakout board, a slider module, a wheel module, a small breadboard, a shift register, some LEDs with resistors, and even a plastic box and battery holder!
