M2M Demo – Lesson #9 : DIY Capacitive Sensor
This tenth project will unleash you do-it-yourself (DIY) spirit so that you are able to build your own custom capacitive touch sensor. The capacitive touch sensor is by far the easiest and cheapest to build for yourself which is why you will be using it in this tutorial’s project. You will build a cusom sensor out of aluminum foil, which will later be part of your project’s circuit. You will use one of the ADK board’s digital input pins to sense when a user touches the sensor or influences its electrical field. The touch information will be propagated to an Android application thats lets your Android device become a game show buzzer by vibrating and playing a simple sound file at the same time.
You will find :
– Arduino sketch
– Android code
– Documentation including : List of electronic components, Circuit diagram , Arduino sketch, Android main class script, and a photo of the result.
You can enhance the code or create new one 🙂
As usual all code is documented.
