Controlling a wearable display using a bitalino EDA sensor
- Arduino Code
- Graph the data from the arduino code running over Serial port
- Scale using up and down keys
- Eagle schematic and board
- Current version is 2.1
Each pinstripe had about 2-7Ω resistance and received about 450mA from a 3.7V LiPo battery via an Adafruit Powerboost 5V regulator, switching on (100% duty cycle) or off (0%) with a transistor controlled by Arduino pins. Each pinstripe consists of a single conductive thread. Snaps on the inside of the shirt provided removable but secure electrical connections to the thread endpoints. A Bitalino skin conductance sensor was placed on the back of the left shoulder of the shirt to hide the sensor from public view and secure it within the shirt.
Fabric enclosures for electronics fit inside the shirt. (a) Skin conductance sensor with electrodes on colored paper for visibility. (b) Snaps connections to pinstripes. (c) Diagrammatic representation of pinstripes, which in actuality were sewn into shirt. (d) Snaps connections with FSRs for override on/off features. (e) Diagrammatic representation of FSRs, which in actuality were embedded in shirt seams. (f) PCB and battery, which were hidden in an interior shirt pocket.
