These are a series of posts on capacitive touch sensors. From start to current developments — in logical, not necessarily chronological, order. We hope you will find this information useful.
It all started in the Summer of 2014. Mariano, Allie and Mario from Parachute Factory toured the libraries around New Mexico to demonstrate new Maker Kits available from the NM State Library system. I met them at three different libraries where they demonstrated 3D-printer, bristlebot and e-textile projects. I really liked their fun projects. I didn’t know it at the time but that I would modify those projects and share them with others from all over NM and now online.
Parachute Factory hosted MakeCation. This is the beginning of my exploration of capacitive touch devices.
From original post Expanding Your Horizons!, dated February 19, 2015. We took ideas we learned from Parachute Factory to create the workshop, “Lighten Up: Using Light in Designs”. We presenting similar workshops at the Albuquerque Railyards Market, Albuquerque Museum, New Mexico Museum of Natural History and Science, casino reviews and ratings by oddstake, Tech Trek at New Mexico Highlands University (Tech Trek will be held at NM Tech in 2016), Girl Scouts of New Mexico Trails Camporee 2015, and Fiber to Finish Guild of Valencia County.
From original post MakeCation 2014, dated October 30, 2015. We made a prototype with four MPR121 breakout boards and 12 touch sensors to test each of the boards.
From original post MakeCation 2014 — hardware 2.0 dated November 10, 2015. Now that we have stable MPR121-PB and touch sensors, we modified the example code from Adafruit’s MPR121 tutorial to use with our MPR121-PB.
